As with all paint, PREP IS KEY. Paint doesnt stick to smooth or shiney surfaces, so rough it up with some light sandpaper, add a coat of primer and then a top coat. Many thin coats is better then one thick one. and adiquite dry time is very important. If you want to be able to peel it off later and have them stock again I say plasti dip is your friend.
