OK, the verdict is in. Or at least I've done the test. Anyway, I'll start with what it says on the package.
CCP 5 Minute HEADLAMP Len Restorer - NAPA Auto Supply
What it is: It says it uses a 1.2 micron mineral (smaller than the eye can see) formulated to restore the optical clarity of your headlamp. Doesn't say what the mineral is. State secret I guess.
What it isn't: Says it contains no silica, silicone, petrol chemicals, acids, waxes, clay fillers or chemicals that can be hazardous to you and the environment. It is a water based product. note: sounds like it wouldn't hurt a living thing. Still, no guarantees. Wash and rinse. Then rinse again.
What it does: Well, the proof is in the pudding as they say so I grabbed my screen door replacement window and polished it a little. No problem so far. But what if I scratch it!!! Well as it happens, that's a lot harder then you think. You know how it is. If you're trying to keep something nice, sure as shootin' it gets screwed up. If however, you're trying to damage it on purpose... forget it. Oh I finally managed put a scratch in it. Had to use a file to do it though. Anyway, I started to try and polish the scratch out. I polished and I polished. Then I polished s'more. And you know what, it started getting better. It took a long time but it actually started to get better. And there were no swirl marks, hazing or anything. Just perfectly clear glass. Now I didn't finish taking all the scratch out as I'm doing this early in the morning and it would take quite a while but I think I'll have to give this product the thumbs up. It actually does what it says it will. Sure, it will take quite a while on actual glass but hey, glass is really hard stuff. Practically hard as rock. Or sand anyway. lol :laugh: So there you go then. It works. Really slow on glass but it does work.
