I fucked up big time /diy/
I tried to repair my yellowish opaque lights and the thing came really nice except for the part where I just right fuck it really high. After applying an oven cleaner foam on them, the yellow just went away. Then I hand-applied a metal polishing product and they came really transparent and bright. Good thing these inventions of mine worked really well.
Now, in the meaning of getting them glaring, I sprayed a finish coating. This resulted in a really clean result.
Then I did something terrible, I let the car under the hot sun before the varnish dried up and it wrinkled badly.
Now my lights look WORSE than the ones in the upper picture and the coating refuses to come out. Tried polishing but does nothing now.

I'm I permanently fucked?
(actual car not pictured).

Squeeze on some toothpaste and brush them for a while. Toothpaste is a really fine polishing agent which should strip the varnish while not biting too deeply into the lens.

>> No.1627890

also tried this but, rather the paste is not good enough or I'm not applying enough pressure or time.
Whats your opinion on using a heat gun, or even a solvent product?

You're gonna have to sand it off, work through the grits, and polish it again

This. Just use a 600 grid and then go up and up.

Bruh, go on RockAuto. I was about to buy the headlight kits and waste a whole afternoon on my GF’s car until I went on RockAuto and got brand new assemblies with new sockets and bulbs for <$30 each. I figured they would be a couple hundred bucks for both but I got OE quality replacements for like $55, definitely better than wasting $30 and an afternoon on the kit for some half results.

Will any toothpaste do, or must I use my diamond whitening toothpaste?

You fucked up, now you must do 8 hours of hand sanding + clearcoat to unfuck them.
Pic related, before I redid them.

>they got some over spray on lights, clay barred it off. Fast forward lights started getting cloudy, I removed the clearcoat.

Honestly if I had to do it again I'd just buy new lights.

This took like 30 min per light.

I chucked the bit up in a drill press and removed my lights from the car and just held them while working them against the various grits.

>> No.1628843

Just using a Polish instead of a clearcoat will just mean it will yellow/get cloudy again in a year or two.
Last sand should be side to side only so the paint holds better and doesn't run.

>> No.1628870

The other side of the rubbing compound is actually sealer and they encourage you to buy more and put more on every couple months

>oven cleaner

Maybe get a headlight polishing kit?

Those aren't OE quality, doofus.

That's the guide I used, and it took a full day of work. Like I said, if I had to do it again I'd just buy new lights and replace them.

Things escalated worse. This is the family car, not just mine. My father found out and now I am in serious trouble. he doesn't let me sand it off, not even be near the car.

>> No.1629427

Nice one anon, I might give this one a try when I get a spare couple of days!

all these "fix_it restoration methods are temporary at best.
unless you want to be brushing and sanding your lenses again every 3 monthes, just buy a new set and dont leave your car parked out in the sun all the time

Don’t use oven cleaner
Don’t use toothpaste
Don’t use baking soda
Or headlight cleaning kits or any other crap like that.
Buy 600 grit, 1000 grit, 1500 grit wet dry sandpaper, a bottle of plastic polish and some cheap cotton rags.
All can be purchased at Walmart for $10-$15us.
With a little soapy water BY HAND sand the headlights through the different grits, then buff with cotton and plastic polish.
No need to use a drill, because those can cause heat. Sanding by hand will take 10 minutes per headlight. Pic related My 1998 Silverado headlight assembly

This is the plastic polish I used on the light assembly. I also use it on my acrylic pen blanks.

>> No.1630966

not bad advice. but ma\ybe follow the procedure by rinsing the lenses completely clean and free of soap or polish residue, then paint with a spray on clear coat. that will preserve your surface as a shiny crystal clear appearance

>> No.1630978

I do that when I want remove the raised letters and have a totally smooth surface. I hate when dirt and wax builds up in them.
