I know its not polish or wax but I have a couple highway chips and need help on correcting them. I know I can get a matched paint pen from Nissan, but do I just dab a little on the chip and let it be? I don't want it look like a bubble of paint, id like it to be flush with the rest of the paint. And is there any clear coat I should add or do i just do my normal wash / wax and it will protect that area fine ?
