I know this one sounds a bit on the strange side so I'll explain. Some kind hearted young chav decided it would be a good idea to use my car for target practice and hurled his/her empty bottle at my car last night. The bottle shattered and has scratched hell out of the rear quarter panel. Some of the scratches have gone through to the bare metal so its gonna need some paint to sort it out. In the mean time though there seems to be a load of crushed glass embedded in the paint which I'd like to remove. The last thing I want to do is damage it further (even though I'll get it painted in the next few weeks) so I didn't want to just give it a go without checking for advice. Anyone got any bright idea's or is it just gonna be a case of taking it slowly and doing my best????
