Saw the commercial on tv, but I'm not sure how it works.

i used dupli-color before but i haven't used "shield" so i cant be of much help. But overall i was happy with their products.

when their touch-up black paint dried i couldn't tell a difference and it has a nice finish. looks very professional.
