who knows plastic?

[sidewaySilvia]

Have a big problem , well to me anyway.. I bought a used jdm , dome light and the plastic was a little dirty with light surface scratches. I used a dremel to clean it using #2 setting at 10,000 rpm.. And ...

The plastic is now scuffed.. Anyone know how to get rid of this.. Aaararrrrrrrrrghghggggghhhh!!!Plus ++ the underside of the plastic is designed with hundreds of tiny grains.. This side is scuffed as well...

How do I buff and restore transparent plastic??

Try the buffing compound and the buffer bit.

I l00ked through the catalog and there wasn't anything for buffing this type of plastic... What is lexan plastic also?? I have been doing a lot of internet searching and stated was " if dealing with a lexan plastic and the scratch or scuff is too deep , you will have to cross- something sand and use professional equipment to buff and restore.. Guys, I also have 2 very small nicks in my windshield .. How can I buff these or remove(fill?)????

Lexan is GE's brand name for polycarbonate. While polycarbonate (PC) is extremely crack resistant, it is notorious for being very easy to scratch. There are a couple of things that you can try to restore the dome light cover. There is a line of polishes made by Meguiar's specifically for plastics. They come in different levels of abrasiveness, and they work pretty well actually. Pick up level 3, 2, and Mirror Glaze. Start with 3 and work down to the mirror glaze. It might take some elbow grease and some time, but it should work.

Hope this helps.

Good stuff c. . I'll give that a shot, I ordered a meguiar catalog like a f'in month ago and nothin came in yet.. I am also talkin to a prominent plastic and glass product manufacturer "janvil" they got some good stuff.. I told them the situation and they said I'm better off replacing it..

So, I NEED TO FIND A JDM S13 DOMELIGHT COVER!!!

how bad are the scratches? if really bad i'd wet sand it first before you use the rubbing compound, might save you alil time and elbow grease.

Bro , I'm not removing paint or anything of the like.. This is pitted plastic we are talking about .. I've talked to several pros and its recommended that I just replace the thing.

So now, the search for the jdm s13 dome light cover!!!

This JDM dome light must be the shiit. I bet you could find a US dome light at a junkyard for about $2.

FWIW, I'm in the lens/eyeglass making business and after we rough cut the back surface of a lens we use a series of fining pads (sand paper if you will) and water to smooth the surface and then a velvateen pad (think soft felt) along with liquid polishing agent to complete the process. Making the back surface of the lens smooth and clear again.

And in the category of information you'll never need ...

Basic processing consists to 2 fining processes- plastic based materials, we use a 15 micron pad, then a 1200 grit pad- poly based materials, we use a 280 grit pad, then a 800 grit pad

So, we he spoke of wet sanding the dome he wasn't completely off in left field.

Good info to know, but this plastic has a multitude of little squares "so to speak" .. I believe this material is poly-based so could I "wet sand" then "polish" this area to a restoration? My bad mecp I just am use to people wet sanding to help removepaint layers and other coats not actual material.
