I replaced my front rotors after about 14 years of service.

If you're ****, you can use an old rotor to make masking templates out of butcher paper; if you're lazy like me, some blue painter's tape covering the drilled holes is more than good enough.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Replacing all rotors - what's the difference, noticed Paige are half the price compared
To ATE coated rotors - no track for this car - it's my weekend cruiser

Coated rotors will not develop rust/discoloration around the hat area. The coating is worn away on the stopping surfaces of each rotor; the remaining coating protects the outside edges of the rotor and ensures that the visible part of the rotor hat is aesthetically pleasing.
Some high-temp bbq paint or Rustoleum works just fine if you don't want to pay for the coating. I prefer to mask off the stopping surface on both sides and just paint the hat area and the outside edge of the rotor.
Uncoated rotors tend to look like this over time:
Well, not EXACTLY like this - they won't ever look like Corvette rotors, but you get the idea.
The quality of the coating will determine how the rotor looks over time. If you want your wheels to look their best, coated rotors (or painting them yourself) are the ticket...
And coated ones will provide at least 30 HP gain!
Damn! C'mon, I got OE new front rotors, painted front and rear rotor hats with Rustoleum and at least two years later they look perfect. Mask the wheel mounting surface, give them two good coats of Rustoleum and you are good to go for a long time. Way over complicating things if you ask me.
I don't like spray-painting drilled rotor faces; I don't want to gum up the holes with paint. But yeah, I'm a big fan of the "DIY rotor coating" thing. I have more than my fair share of high-temp spray paint in the garage. If you're ****, you can use an old rotor to make masking templates out of butcher paper; if you're lazy like me, some blue painter's tape covering the drilled holes is more than good enough.
meh, it's not worth my time or money to DIY this. spray can of paint will be between $10-$20 then throw in a hour or 2 for the actual work....I'd just pony up the extra and be done with it.
Just for the record, a can of Rustoleum from Ace Hardware is about $5. Sorry I even posted on this one. I replaced my front rotors after about 14 years of service. So it would be interesting to know/learn if "coated" rotors last that long without any touch ups. Guess then go for it...and let us know in 10 years how they hold up.
They hold up quite well. I have them on both my daily van and car and there's very little rust build up on them. they are nice and silver vs the nice rust colored color of the brake calipers.
to each their own. if you have paint lying around and want to spend the time maskin rotors surface and so on, knock yourself out. I'd rather save time by just buying coated rotors.
spray paint with heat paint, the whole rotor, inside and out, middle internal vents. When they are new and pads will remove paint on the surface where the pads touch. everything else will be rust free
