Hi, new to the board and wasn't sure if this has been asked before. I have a '73 SE that has a white interior. I want to change to black. I am going to have the seats covered, but didn't want to spend all the $$$ for new panels since car is not stock. I have heard of SEM paint for the plastic, but is it also for the vinyl? I have heard the term dye used. Is that also for plastic and are there 2 different processes.... paint and dye?
