I saved this for last... How do you guys suggest I apply it? There's tons of black trim (old BMW) and I gotta do the tires too. I have a sponge thing for the tires... But what about the trim and mouldings?? Is it ok if I over spray and get it on the paint? It's waxed and dust-free right now, don't want to screw it up... Or should I spray the 303 on a towel or something and rub it on the trim?
