Seat paint

Been thinking about painting my seats silver to finish my interior off. But only the center area not the whole seat. Does anybody know how long this stuffRIGHT HERE would last if I did this? I'll be using the "tuner" silver. Also if you think it'll look dumb don't be afraid to say so. People said not to put the mustang on my door but I did and it turned out great.

So far I've painted the center console, door handle "cups", switch bezels, Mustang logo on steering wheel, and Mustang lettering on passenger dash, and all the vents.

I'll basicly be painting the light grey area of the seats.

Don't mind my little alien mascot friend.

$200!?!?!?!?! If I had that kind of money my car would be running 10's. No offense, but that's just way too much for me.
