So I have a Messinger metal flake seat that has a lot of discoloration from probably being in the sun, I've washed it heavily with dawn and water, simple green, treated it with 303 protectant as well. since the vinyl was formed over the seat and can't be removed, I've already cleaned all the rust off the exposed metal and was prepping it to repaint. During the prep, i tested part of the underside with acetone, it cleaned the stubborn rust spots off the vinyl. although it left the material feeling sticky. I retreated it with the 303 and it seems OK now. Has anyone tried cleaning a whole seat with it? Or does anyone have any suggestions on how to get rid of the the rest of the damage? I know the seat is pretty faded, but if i can get some sparkle back that would be rad.
