Default yellow headlight shells

It took me about 3-4 hours by hand, but I'm a perfectionist and stuff like this usually takes me a long time. If you decide to use any type of machine to do this, be careful... plastic is very sensitive to being over-heated. I only did the passenger side headlight, the driver's side was replaced not long before I bought the car due to the previous owner having an accident. I will probably pull the driver's side light next weekend and hit it with the Novus polish.

Here is an after pic:


Here are all of the pictures that I took showing the progress: linky
Was all of the yellow on the outside of the shell or did you have to go inside?

LS1sounds, I have a few noobie questions, because I simply do not know anything about this type of work or the tools. When you say 800 grit, 1000 grit, 1500 grit, what is grit? Is it just different sandpaper?
Can you explain "wet-sanding" more for me. I don't know if it means to keep the light wet while you rub it with the "grit".
Also, is taking off the headlight hard and or safe?
Where can I get the proper polish for these headlights?
Thank you for any help you can give me.

Yes, the grit is (IIRC) the amount of particles per square inch of sand paper. The higher the number, the finer the sanding. The reason you start off with a courser (lower number) grit is to remove material faster. You could do the job with only 2000 grit sand paper, but it would take you for ever as the finer the paper, the quicker it clogs up.

Wet sanding is used a lot on automotive paint jobs as it removes the orange peel and gives that nice, deep polished look. By using water while sanding, it helps the sandpaper from clogging up so fast and also helps lubricate/polish/cool the surface being sanded. I actually sprayed a bit of WD-40 cleaner on my paper when doing it, but I wouldn't advise that.

The lights arent too hard to remove, any $15 dollar manual from an automotive parts store can show you how. There maybe steps/pictures already here in the forum's archives or on Install University's site.

The plastic Polish and sand paper can be purchased from most automotive paint supply places and even Pep Boys. Meguiers, 3M and others make the polish.

thanks a lot rocndav

and i just assume that the polish has all the instructions i need on it?

You'd probably want to spend 20-30 minutes per grit at least. I spent 30 seconds to a minutes, doing only half of the headlight to see a true before and after. I was amazed how it came out with spending so little time on it.

The plastic polish is just a final polish. you use it as you would polish a car. dab some on a terry cloth towel (or old athletic sock, inside out) and rub away

So glad I found this thread...I was going to order new headlights today, but I'm trying this first. The headlight money can go back in my "mod fund" jar, ha ha.

I'm not sure, I've never examined that type of headlight. Some manufacturer's use a different coating over the plastic lens to protect it. This coating is too hard to sand/polish, and sanding it can potentially ruin the lens. I'm not sure what type of lenses are on the Grand Am?

I didn't know what was on the Camaro either, but my lenses were soooo bad I just took the chance. Halo's were the backup plan if I ruined them!
