Used Acetone, Lights Look Terrible

[MassWineGuy]

I thought that after sanding my plastic headlight cover, rubbing it with acetone would make it clear. But it streaked and fogged it up worse. Do I just need to wet sand again w/400, 800, 1,000, etc. grit?

Thanks a lot.

Welcome to AGO.

Did you polish at all after sanding the lights?

[Mike Phillips]

Yeah....

Acetone is a very hot solvent. What it did was melt the plastic.

Just re-sand and the polish, skip the acetone.

Shows before and after for sanding and then polishing...

I didn’t polish after sanding. Should I use that Plastic X stuff or some rubbing compound? I think I’ll need to use 200 grit first. No way am spending $100 on some kit.

Thank you.

200g may be too course. Start with a 1000 and move up or down as needed. When it becomes fairly clear, compound and polish. Acetone and plastic don't mix well.

Like Mike Phillips said. AFAIK, Acetone will eat plastics like candy. Melt the living daylights out of it.

I'm not sure using rubbing compound is a good idea. Plastic X is a decent plastic polish in a pinch after you sand it all out, but I got far better results from this Wolfgang kit.

Wolfgang Headlight Kit.

While it might still be a bit pricey at $60, you are getting a small backing plate, drill adapter, pads, and the products needed to polish and seal the headlights. I've been much happier with the results with this kit vs using just Plastic X. The lenses come out clearer and the included sealant greatly slows down the yellowing/hazing process.

I do a lot of headlights. You need to start with 800 dry, then 1000 dry, then 1500 wet, 2000 wet, then a heavy compound followed by a good polish. Lot of work, but you need to remove the damaged plastic. I have gone down to 400, but never 200.
