I do this every year about this time. When your hotrod is your daily summer driver, you collect stone chips. The ones that aren't from flying gravel are generally made by myself in random fits of stupidity---dropped wrenches, scratch with engineering ring, ---dumb stuff. I still have a quart of paint left from 4 years ago. It reverts to 1" of solid sludge, and the rest is about the same consistency as Naptha gas.--after 1/2 hour of stirring, I mix it up on the bottom of an upside down soup can. Three drops of paint, and one drop of activator. I have a tiny little paint brush, about half the size that a kid uses with his first water paint set. I go around the car looking for stone chips, and generally stick a big old peice of masking tape near the chips so I can find them again. Then I go around with a little bit of Prep-sol on a rag and wipe off the accumulated wax. then I walk around and dab---and wait half an hour---then walk around and dab again. Generally I do three applications to fill in the chip holes. If I was really good, I would wait a week untill everything hardens up, then CAREFULLY sand down the high spots, and buff it out. ---but I'm too scared that I will screw it up and end up making a mess!!! This has become a spring ritual at my house. And every time I'm out with the car and people say "Wow---I don't know how you drive it all the time and keep it looking so nice!!"---I have a little chuckle and don't say anything----.
