I am repainting a spot on my hood that I repaired. I am curious as how to make it look the best? Should I completely repaint the side of the hood and clearcoat it or should I just repaint area I repaired and then clear coat the entire half of the hood? What will look the best. Also if I am just recoating clear, do I need to scuff sand the old clearcoat with 400 too? will it still be glossy if I repaint over the original clearcoat with it being scuff sanded? thanks for the help!
