Here my process.
1. I use Blue painters tape to section off the chip.
2. I then use GM touch up paint & apply 2 to 3 coats using a match head. remove the tape.
3. I wait a few days for the blob to cure & take a credit card & I wrap a yellow 100% cotton polishing cloth making 2 thin layers around the card.
4. I then take ACETONE on my finger & dab it on the yellow cloth. (dont put to much on, just a little will do) I take the wrapped credit card & gently go back & forth over the paint blob until it's now level with the paint surface.
I then take GM polishing compound that comes with their touch-up kit & apply the polish to the now dull touch up. I then take ZYMOL Wax cleaner & buff out the paint. Then I take Rejex & apply it as the final step.
Then it's off to the refrigerator
for a cold Corona & lime to admire the touch up.
