I can tell you a fool proof way to repair paint chips, but it can be a pain in the ass. The hard way: load some thinned out (with laquer thinnner) touch-up paint into an airbrush, aircompressor required, and spray over the area. Then let it dry for a few minutes and use some Mequires Cleaner (step 1) on a cotton towl to remove the excess, as if you were waxing the car with it, and what is left over will fill in the chip. Note: you need to make sure to get all overspray off, which is what makes this a pain in the ass.
The easier way:
Take some touch-up paint on a fine point brush and fill in the chip. Then take your finger and rub the blob of paint over the chip and surrounding area. Repeat several times. Then take the Mequires I described above and remove the excess. Note: It will look really bad until you use the cleaner, dont let this worry you.
Either way will work every time, unless the chips are really huge. /phpBB/images/smiles/icon_wink.gif
BTW: As promised, I tried out GS-27 with the Crayons. That stuff sucks, although it may work if you have a white or black car. I had a color match problem with torch red.
