The other reason I did mine, was that the wheels were VERY difficult to remove, and the cause was easily seen by the galvanic corrosion residue on the tangs of the wheel hubs.

Did yardwork, washed two cars, and ran 3 miles (3 more than the Porsche).
Use aluminum look engine enamel in a spray can though

I did mine last Fall and used the Caliper Paint - Black of course.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

After detailing my 18" summer Twists yesterday, before I put them on I wanted to finally rid my car of the rusted ugly looking rotor hats! So, I followed the simple procedures I used when I did the same thing to my 944, and got excellent rust-free results. I used BRUSH on Rustoleum 'hammered' silver. Only thing I had to mask were the calipers. Brushing leaves no brush marks since the paint cures with a cool hammered metal look. Check em out:
After painting (just found a before shot from when I first picked up the car)
Rims mounted, no rust = 100% better, IMHO!
No, I talked about wanting to do it, never got around to doing the 996 rotors. I did use the same paint on my 944, maybe that's what you are thinking of?
That might be it. I know I bought the same paint on your recommendation. I've not had a chance to do the job yet, the can is still sitting on the countertop in the kitchen (and annoying my wife). I was afraid for a second that you were having to redo the paint job because it wasn't durable.... if that was the case I might have been going out to buy a different paint.
Hopefully I'll manage to get mine painted in a couple of weeks when a hole opens up in my calendar.
I had no trouble with durability on my 944, and the brush on paint is extremely easy to work with. Any excess gets scrubbed off by the brake pads.
Also, this was the first time using jack stands on the 996, and it couldn't be easier thanks to the tutorial on Rennech.org.
Believe me, I am a total wimp when it comes to jacking cars, yet I had ZERO problems getting all 4 corners onto the jack stands. Car is solid as a rock on 4 stands if you follow the Renntech instructions.
Took me a year to do it because I am lazy too! Finally got to it after looking at the rusted hats all winter. I am a wheel guy, and nothing looks nicer than clean rims and no rust on the rotors (can't avoid the rust in the little holes though)!
The paint dries in less than an hour. I left the wheels off for a few hours, just to make sure. But it does dry fast. Especially since you are not slopping on a thick coat. Beauty is, it stops rust, so there shouldn't be any rust bubbling through the paint in a year, etc.
OK, you win!
My weekend project was installing a Touchscreen Pioneer nav with XM, Bluetooth and iPOD interface.
It looks and works really great and I did not have to cut any wires so I can always restore to stock
I will post some pics this weel.
It's a Z1 that I picked up here on Rennlist, Bluetooth, XM, Sirius and iPod.
really nice unit, It's just a software (hard Drive swap) upgrade to make it a Z2 or even a Z3 so I will probbaly do it.
I am pretty happy with the way it sounds with the factory Bose amp and speakers.
Andy, looks great. This is on my list when I do my calipers. I am so glad you posted this re the brush on paint because I bought a spray and I was dreading the tape job. Off to Home Depot this week!
I ASSUME all the heat stays in the disc and caliper area, not sure though. It might get hot, but not hot enough to bother the paint. Someone correct me if I'm wrong.
I also painted my hats this weekend before installing new rear rotors. I used aluminum look engine enamel in a spray can though. Easy to do with the rotors off the car. Now the calipers look terrible.
Stefan
I could never figure out why the tophats aren't powder-coated at the factory. Who wants rusty-looking disks?? They look like crap when they're all rusted.
Great job! This is gonna be my next project, although, like you, I'm kinda lazy, so it might be year-long thang ....
It really doesn't take long to paint the rotors, maybe half an hour after you get the car on the jack stands and wheels off.
Has to be a money saving thing. Why paint it with a thicker coating if it would cost .10 more per rotor, etc, etc.
Sad thing is most other cars you see around don't have rusting rotors.
I'm going to do it this weekend and clay and wax the inside of the wheels while they're all off the car.
To the OP, you still aren't having a problem with the paint coming loose? I'm concerned about tempurature like others, but really want to brush rather than spray.
Yup! If I had the energy, I would have painted the bolt heads. Or, better yet, I'd buy a set of stainless bolts on ebay.
For now, I moved the most rusty bolts to the back wheels, where they are burried in the rim.
I never had this paint flake off, it seems rock solid, like it bonded with the rotor. Give it a try!
I just did all 4 of mine today, with Duplicolor high temp caliper paint (with ceramic)...less than an hour total, once the car is already up & wheels off. All 4 of my wheels are getting refurbed, straightened, trued, welded, powder coated, so the car is up on 4 jacks for a few days. Perfect time to do it. I'd post pics but I have to resize them and upload them. Personally, tho, I'd much rather put 5 or 6 light coats sprayed than hand brush. The masking takes like 3 minutes a wheel, and the finish is so glossy you can see the holes in the rotor reflected in the paint. Rock hard finish, too..All the time is in the prep, derusting, etc, which you have to do regardless. The other reason I did mine, was that the wheels were VERY difficult to remove, and the cause was easily seen by the galvanic corrosion residue on the tangs of the wheel hubs. Even painted, I'll still use some anti-sieze on the tangs to be safe.
I hear ya, but my 'prep' was wiping the rotors down with a towel soaked in simple green. That's it. And, I really wasn't going for a showroom paint job on my rotor hats - just something that looks better than rust. I also didn't want to go anywhere near my car with spray paint. No matter how I mask something, spray paint always tends to wind up somewhere I don't want it!
AHHH, when I post my pics, you'll see why that was not possible for me!! My fronts (which are about a year and 6k miles old) were SOLID 100% rust on all non-pad surfaces...impossible to paint without a lot of prep. My rears were about like yours, so prep was much shorter
I did mine yesterday also. I sanded down the fronts because they were rusty. They turned out well. I took pics but have to figure out how to resize them for posting here. I have doubts about the paint lasting due it not being high heat spec'd. The wheels get hot and they are attached to the rotor hat so I assume they get hot as well. The rotor disc certainly gets very hot. We'll see. If the paint fails it's no big deal as this was an easy job and could be redone with the caliper paint, even though I'm not looking for a high gloss look.
I uploaded some pics. The first is one of the fronts before. The second is one of the fronts after being sanded. The third is after painting but before wheel mounting. I'll take another with the wheel on and the paint edges smoothed from the pads.
Andy, yes same paint brushed on. The reason they were so rusted (just the front ones) is because when I painted my calipers late last fall I was going to paint the hats then so I prepped them. Which means they were down to bare metal over the winter. Anyway, after I finished with the calipers I was exhausted and didn't feel like messing with the hats. That's about 6 months of rust.
That's a nice gloss on that finish!!! As glossy or glossier than mine..easy to see the rotor holes. Mine were bit rustier than yours, but I did more prep and got 99% of all the rust off, then wiped down with acetone before I sprayed. I'll post pics tonight. deckman, you painted your black calipers, red? With spray on caliper paint?
Perry, I painted the black ones red using Duplicolor caliper brush on paint. It took at least four coats for the calipers if I recall correctly. I did spray on a couple coats of clear. I should have done my hats then when the car was masked, but i was shot and done with it.
Funny you mention the high gloss on the hats. I wasn't going for that really, just wanted to get rid of the rusty look. The flash from the camera makes it appear more glossy that it really is. This was a truly easy job. Took the opportunity to clay and wax the inside of the wheels while all of them were off.
Yeah, that has been the problem for me. The can of paint sat on the kitchen counter all winter. I was glad to finally have some time to fit the job in this weekend... the combination of working on the car and the yard and I'm walking around as sore and stiff as a 70 year old.
My car is disgusting and in need of a bath now. The combination of pollen and mud from road construction (in 3 places) on the way to work there's no hope of keeping it clean right now... I'll defer giving it a bath until next weekend.
Wayne, rgw top hats look good!
BTW - the above comment is pathetic... feeling like a 70 year old? Wait until you get as old as Phil.... (OK, OK... and me), then you will feel like 107 years old!
Yeah, I really have no excuse. I'm at the gym everyday, but a full day of jacking the car up and down and doing yard work and I'm walking around like... well, as you said, like Phil.
I was actually kinda annoyed as my torque wrench scraped one of my wheels (in two places) when I was setting the torque on the wheel bolts.
I need another weekend.
After reading this original post ---- I did mine last weekend. I used spray paint I had in the garage. Rustoleum --- Sterling Silver. Covered the brakes - Rotors and went to town. I also sprayed my lug nuts and locks with some Chrome paint I had.
Looks great. Thanks for getting me motivated.
Chuck 951
Tell me about it. I wasn't happy - especially when I realized that I had an extension adaptor sitting in my socket set that I could have used.
Oh well. I cleaned the spot and put a couple of touches of clearcoat over the marks... sadly they are noticeable.
Hey, speak for yourself! Did yardwork, washed two cars, and ran 3 miles (3 more than the Porsche). And Wayne, we know I'm LOTS older than you! BTW, did you get the pics of my brother's cars I emailed you?
Thanks, they were that way from the PO, and he had a garage that the 996 was in since he owned it...I know it unfortunately would sit in the garage a lot, based on the miles and what he told me. The rotors are only a year & 6k miles old and are Porsche rotors (based on the stamped info that amazingly became crystal clear to rear even after rust removal & painting. Anyone else notice that the replacement rotors rust so fast and bad as that?..BTW, I ALWAYS keep a 4" extension with my torque wrench because of a similar alloy scratch on a a different car years ago...pissed me off that I was too lazy at the time.
You win "Biggest Improvement" award! Isn't it nice to look at your rims without seeing RUST in there!?
+1 on the extension when using the Torque wrench!
Yup, pity I had to learn the hard way. I hadn't realized that in certain positions the curve on my rims would rub up against the wrench. I was not happy to find out the way that I did.
Yeah, well, I guess my yard work yesterday emphasized a muscle group that I've not been exercising at the gym.
Now Tim, I have to defend Phil - he's in great shape for someone that drives his Porsche the way that he does.
Sorry to bring up an old thread...I'm about to undertake a rotor painting session and wanted to do the brush on hammered rustoleum paint as well.
Any updates on people that have used this paint on how it holds up over time? Heat, rust, etc?
Thanks.
I have used it and so far it has held up great, but I do not drive in salt/snow either. It has been about 7 months and around three thousand miles or so.
Hi Folks
I know, I know, it's over a decade old. I ordered some of the
hammered silver rustoleum
hammered silver rustoleum
brush on paint and on the can it says heat resistant to 200F. Since the Rotors on a street car can reach 400F, I'm thinking I may have wasted my money.
Does anyone have first hand experience? I guess I can paint one hat, and see how it goes. I'm doubtful that it will burst into flames on me, but you never know. I don't want to end up looking like a very ill prepared 'Ghost Rider'.
If it matters, I'm not hard on brakes, I'm more of a read the traffic and let off the throttle type.
As an aside, I've never understood racing to the next stop sign or red light....I like accelerating away from them, but once up to legal speed I tend to match traffic flow as much as possible, and leave plenty of room between me and the next car in front. I'm a little older, a little wiser (sometimes). In fact, I have had tailgaters behind me, literally pull out and pass me, consuming my buffer zone. I just let off the gas and create new. I don't take anything on the road personally. Everyone has a story, and that aggressive driver, who knows, might be rushing to save a life. :/ Road rage is an awful thing, don't let it get you! It's hard to be angry driving a 911 amiright?
Sorry for the thread meandering...
I sprayed my rotor hats with some grayish Rustoleum spray paint years ago, and they still look good. You will be alright, just don't paint the wheel mating surface.
You can probably try a Two Part Durakote aerosol kit. It's pretty durable and used in the firearm industry.
