Hi i have a '99 Mustang... the seats are made of some kind of grungy material... i want to say something like woll, but am not 100% sure... i know they arent leather or a smooth fabric.... i would like to paint these seats so i can get them to match the other interior of my car... what kind of paint would work for this? Duplicolor Vinyl / Fabric paint? if i do paint the seats, will they feel grainy afterwards? plz help me out!
