Update...
Finished the third coat and cured with heat. Remember this is my second round of fixing these chips.
I tested with a light sanding and the third coat seemed to be hard enough to smooth out without issues. After sanding the touch up spots smooth I noticed there were still tiny areas that didn't get filled in. This is important and applied another round of base coat. So, that makes four. You'll have to understand that these chips in the paint were deep and fairly good size. When a base coat is applied then cured it tends to shrink and leave a cavity where you applied paint in the chip. Again, it is important to use thin layers and have patience to get just the right coverage.
Today I will again lightly sand out the surrounding high spots and smooth the surface. If a fifth coat is necessary I will spend some time doing that and let cure. If a fifth coat is not necessary I plan to buff out the spot to a high gloss finish, clean and prepare for the top or mid coat.
This is where I am at, more to come...
