Most auto shops stock this product to clean clear plastic and perspex, I don't know if this is the same one they use on aircraft domes which was the one I bought last time, see;
We were away recently and DH managed to 'bump'something that had red paint on it. Marked the perspex on one of the windows. Any ideas on how to get the paint off without 'clouding' the perspex? Thanks, Jay-Jay
Interesting. Wouldn't wanna use anything that might scratch. How about the stuff someone suggested for removing tar and bugs - 50/50 kero and detergent? I got some old gum off the inside of my windscreen today with kero.
