Ok so i was thinking , i want to paint my mudflaps the same colour as my car, but if i do, i would paint them and clear coat them, then later if i wanted to trim the mudflaps an inch or so from the bottom of the flap, i would cut them with shears but would that mess up the paintjob on them or not? and if it does then if i want to repaint, do i have to take off all the old paint or can i paint on top of a clearcoat? or what?
