We use SEM on some stuff but I dont know for sure about if it will hold up on seats. PM kurupt (not sure on the spelling) He would be the one I would ask. Just look at some posts here and see if you can find his name or he might read this. Also one other person is enufftalking ( not sure again) he might also know.
there ya go.....ive used that before through an airbrush and it worked good....i cant vouche for how long it will last but whenever i have done work like this i have always scratched at it to see if i could damage the coating and this stuff didnt come off...i havent been able to peel the sem dye off my younger brothers seats so i would say that it works...if it doesnt ill just get a diff dye and do them again
