where did they come from? And how do you fix a paint chip by yourself?
First, the latter question: Neilda came up with a company that has a NEAT "kit" to do 'zactly that. Go to www.lanka.com and Bob's yur uncle!
As to how the chips got there ...'been on a any gravel surface (like a shoulder) and made a tight turn? Small grit & stones stick to those F1 Supercars real easy... as you turned, the tires could'a picked up a small rock & launched it. OR - the darn things could'a just hit from a car straight ahead of you and landed on TOP of the fenders instead of somewhere else. They ALSO could have come from ONCOMING CARS. There's no way to know.
