Windshield - Prepsol/3M Adhesive Remover

It was quite by accident that I stumbled across this, but I ended up using some 3M GPAC (08984) on my windshield and was absolutely stunned by how well it cleaned it. I did half the windshield after cleaning the whole thing with clay and IG...



Toss the towel (cotton) onto the 3M'd surface and it slid right off. Toss the towel on the IG/clay only surface and it stuck. It solved two problems - clarity and wiper skip. I've learned to deal with the chips and pock marks of my relatively upright windshield... It was like using a glass polish without all the elbow grease.



Now, I realize some windshields may have a coating (or is it IN the glass - that BMW/Mercedes bluish hue) and surrounding bits (wiper blades, vinyl trim, etc) will NOT react well with this stuff and painted areas would need to be re-waxed if this got on them, but WOW... I then did the inside of my windshield. :D (would have passed out if it weren't a convertible!)



Is there any situation in which this stuff would have a particularly bad reaction with exterior glass? I would only consider it on windshields... Obviously tint would not react well, but on exterior glass?



Thanks!
 
Shouldn't cause any trouble, I used it on a windshield that hadn't been cleaned in months atleast, that I needed to be clean for my driver's test. (sap, bird bombs, I don't want to know what else). Did a helluva job on the gunk. (still failed the test though :()
 
animes2k--As previously stated, the Prepsol shouldn't hurt glass, but definitely keep it away from anything coated/tinted.



Try Autoglym's Glass Cleaner/Polish for routine windshield cleaning. It is solvent based like the Prepsol, but not as overpowering in the interior.





Autoglym's Glass Polish is great for exterior or interior glass. It is a solvent based polish unlike liquid spray cleaners and it really cuts the vinyl haze build-up. I apply a few dabs on a paper towel and spread it across the windshield. It dries almost instantly and buffs off with a clean mf to the clearest streak-free windows I have ever seen.
