It's not a big bugger of a job

An important thing to remember is that bug strike marks need to be cleaned off as soon as possible. As the bugs slowly decompose, they have some nasty acids in them, which means if they are left on the paint surface too long, they can badly damage and etch into your paints' surface. It can become a very big bloody job to then remove those marks and is usually best done by a professional with a machine polishing system. So clean them off before it gets to this!
