I need some advice on how to paint the front lip of the Miata. Mine is so "sand blasted" that can use some new paint. I am thinking of using the TCB spray can method. Other than prep the area with some 800 grid sandpaper, wipe it down with some paint thinner or acetone, and than spray, is there anything else I have to do? Do I need wet sand it with 1200 grid between coats? Or one coat is all is needed?
