I have witnessed somebody ruin a faded bug shield with laquer thinner. I have tried Miquiers plastic polish. Can't get the faded look out of my bug shield. Any tips?

 

I doubt it would work for something that was messed up with chemicals like it sounds yours was, but I know alot of car show guys that shine interior plastic (like speedo lens, etc) with baby oil.

 

Check out the speedymetalpolish.com web site there is a 2 step product that will work on your plastic bug shield. It will even clean up etched glass.

I bought a used broncoII with a weathered bugshield.
I first tried Meguiar's, that didn't cut it, then Novus Heavy scratch remover, this made it worse, i couldn't get the stuff off.
I had a bottle of NicSand Aluminum oxide sanding gel that I had bought for some odd reason, so I figured what the heck.
It came with one of those sponge buffers you put into an electric drill.
Well it took off all the Novus and did a good job of removing the haze. I finished with the Meguiar's to bring back the shine.
You have to watch using the buffer, the edges of the shield cut up the buffer, I had pieces flying off.

 

The best stuff for plastic/acrlyic is a product called PLEXUS. It is a spray cleaner/polish made just for plastic. It fills haze/small scratches, and leaves the surface very slippery, so dust won't stick to it. It has been used on the canopies of fighter jets, and I use it on scratched CD's/DVD's.

I have to agree with using PLEXUS, I have a motorcycle with a plastic windshield. Plexus makes it look like new again (it kind of smells like Pledge furniture polish, maybe it is!)

 

I'll tell ya, don't know if they are the same but I use Lemon Pledge on my MCs both at home and at work. We also use the pledge on the lenses of the of the lightbars when they get hazed and it cleans up the light scratches very nicely.

 

Lots of good ideas. I looked in the shed for some alum. polish. I found NAPA Buff Ease. What the heck, couldn't look any worse. All of the trash in the plastic came out. It looks almost brand new. Thanks to all.

 

I have never tried it on a bug shield but I know that cheap paste style toothpaste works well on headlights and many other plastic parts. Its work a shot.

In the air force we used a liquid polish especially developed for the plexi-glass canopies on aircraft canopies. PLEXUS looks exactly like what we used to use.

My guess is it's the commercial version with no chemical difference.

 

Where can you buy Plexus? amacki4353

 

I use Mguirres Plastic polish on a clear Lund. Originally I purchased a Clear Shield and painted the back side to match my truck. That was 5 years ago and it still looks new.

the Plastic polish works on the dash lens as well. Any Auto parts store that sells paint to body shops usually stocks it.

I read on another ford truck forum that you can use peanut butter. I'm not sure of all the details, but the before and after pics looked good.
