Tip For Scratched Plexi Windshields

[oldgeezR]

A long time ago I picked up a tip from a co-worker,when I was complaining how much the replacement shields cost on a Face-shield. He was a "bodyman" in a paint shop,and he told me to use Glazing Compound on the scratched up shield...dab a little bit on a soft rag and work it in circles until the compound disappears. So I did so and presto, no scratches! Now I have used this procedure several times on all sorts of plastic lens type material...in fact just now I used 3M Rubbing Compound,(fine cut) on a tinted windshield on my fairing,which is plexi-glass, and it looks brand new.This works with surface scratches the best,,,DEEP gouges would not be an option. I use the 3M brand because it has no silicones,waxes or fillers in the ingredients.Try this on your plastic/plexi-glass windshields,helmet shields,etc; and you'll be amazed. Edit 8/29/09: I recommend a good brand of "glazing compound" as a final coat after application of rubbing compound, for extra protection and removing any clouding or very fine scratches.-R.G.

Sure thing...but not too sure about availability in your part of the world. This is the exact product I have,,,but 3m makes like 5 others too.Google "3m"...look under "R=Rubbing compounds" for full line. I will swear by this particular type in link.

Something else that works well is Brasso metal polish. It costs around $3 for a 8oz can. The stuff is awesome. I have used it on boat and snowmobile windshields and my helmet visors. Just dampen a rag and rub it in. For windshields I use a orbital buffer. I had a boat windshield you simply could not see through due to milky fogging. In short order this thing was crystal clear! No one should have trouble finding this stuff.

Fair warning for any glasses wearers tempted to remove scratches - polishing prescription lenses, especially strong ones, become distorted and coatings are easily destroyed. I was desperate enough to try this years ago and ended up stuck using my cheap spares for entirely too long.

Good point.I wear glasses and a spare pair lost their supposed,"Scratch Proof" coating after polishing but as they were spares it didn't matter.

Give this thing a try. It's made for headlights. We used to sell these by the case full when I worked for NAPA.
