So, i think i'm going to try my hand at plastidipping my fake fuel cap on the back of trunk, i plasti dipped my mustang on my grille yesterday and it looked good, but it was easy to tape up. On the cap. im not sure if i should try and tape a circle around it or should i put a square on it and try to peel the plasti dip off the paint and hope it doesn't stay. I don't want to paint the entire thing just the chrome outter part and leave the black inner part normal with the mustang emblem, well this probably didn't make a lot of sense, but yeah. If you need me to clear things up just ask lol..

 

I did mine a while back.

I put note cards on the outside circle. And for the inner circle to cover the "GT" I taped it off. Just take your time and tape it off right And you'll be fine. Took me 15 min to tape and paint everything

 

I like urio's idea. But I would use a note card and cut it out in the shape of the inner circle and tape it down to cover it up. Also I'd use the note cards around it as well.

 

Find a coffee can or something big enough to cover the "inside" (pony emblem, etc...)

I did the opposite and plasti-ed the emblem. The gas cap one isn't as thick as the fender ponies.

Point is, there's a lot of grooves/curves/details that you'd have to peel around to get what you want. Considering there isn't a lot of depth to the cap, I'd think it'd be harder to peel the plasti-dip off in only certain spots. Just my .02.
