I did mine by hand and every time I changed grit I just sanded in a different direction.

I used Juice Swirl Remover because I had it on hand.

I actually used toothpaste and a lambswool polisher on a set of Mercedes headlights.

I've recently did a pair of Honda lens and had to spend a fair bit of time with my buffing pad using a paint swirl remover type polish to get good results.
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.

I am trying to restore a pair of 996.2 headlights. I have twice gone through the following steps and still ending up with fine scratches at the end. The second time around I took longer on each step to be really sure I was not leaving scratches behind.
320, 600, 800, 1200, 1500, 2000, 3000, 5000 grit. Polish and buff.
I am using 75mm discs wet with a drill pad.
After each step and spray and wipe with a fresh clean microfibre cloth.
Any tips? I am finding even at 5000 grit it is still too cloudy to see what step I have gone wrong.
It looks OK from arm's length. But up close, I think they are 800 grit scratches still left behind.
What are you using for the polish and buff stage?

I actually used toothpaste and a lambswool polisher on a set of Mercedes headlights. worked a treat but took a while.
My neighbour used a head light restore kit and hand polished the dullness out for his wifes mazda 6, also looks great.
Sounds like you are on top of it and maybe just need to persist a bit longer?
I used Juice Swirl Remover because I had it on hand. However I was surprised how hard the plastic lens were and the time it took to achieve “clarity”.
I gave up on the scratches. I did use a cutting compound to get the finer scratches out but some deeper ones were left still. They were not deep enough for a fingernail to catch, which was a metric followed by the guy at Repco as being not bad enough for the final 2K coat. So what I found is when I applied the 3M film I am using at the UV protectant, the scratches vanished within the adhesive of the film.
Great result!
I did mine by hand and every time I changed grit I just sanded in a different direction. Top to bottom, then left to right etc. Worked well.
Did you source the 3M film locally? I'm about to do mine again and want to try it.
Cheers Jim.
Got the film from Paintgard.com.au
Keep in mind the size of the 996 lights, you need a 50cm by 50cm peice of film.
Start squeegee at the middle section between the fog and main light as there is a tricky set of shapes there to press into.
The brilliant thing is it's so easy to take the headlong on a 996 out to work on it seperate from the car.
You can use a headlight or plastic polish to finish off the lenses.
Pelican Parts, FVD and Suncoast Parts all sell headlight films that you can get in various colours or clear depending on what you are looking for.
That’s why the fried egg exists. The Toyota experts brought in to fix production costs worked out how much time would be saved with a single light unit that went in quickly.
