Clay Bars / Windscreens.

[Poorboy_racer]

Some time ago I put a post up on here saying soon after using a clay bar on my mini windscreen it smashed, I suggested there may be some link. The response was such that I felt silly for putting that post up in the first place. Most of the responses were along the line of…….you idiot, how could a clay bar possibly do anything to your windscreen? As I didn’t get one single response accepting that it was a possibility, I thought ok, maybe it was a coincidence. This weekend was a British Car show (no jokes about piles of rust and broken down cars thanks) I had decided to take the Mini to. As the screen was getting a bit hazy I thought ok I will try the clay bar on it. It bought the screen up a treat, very clear. Set off and as soon as I got on the freeway guess what? No stone hit the screen, nothing, it just shattered!
Exactly like last time. I know people do use clay bars on windscreens and I can’t find any references to them smashing so maybe its unique to classic Minis or something, anyway, Im never using it on glass again. Im convinced that it had to have done something, no idea what or how. Im writing to the manufacturers, there is no warning about not using it on glass, I will post the response (if I get one) here. Fortunately I did have a spare screen that’s now been fitted. Not happy about all the chards of glass in my cars vents and scratches on the bonnet, though.
