When I dye any interior pcs all I use is lacquer thinner, I wipe down the entire panel let it dry/evaporate, wipe it again, and again, and again, until the panel actually "bleaches" out, black will turn grayish, E body panels are rather pebbly/grainy, so you need to saturate the panel, but give the lacquer time to evaporate and the plastic time to "harden", as lacquer thinner softens it....no adhesive dye prep, just a light tack coat of the spray dye (I'd spray it from a gun personally for best results)let it set up then just a few medium coats until coverage is achieved, too heavy and failure is in your future, I'd also spray a coat of low lustre clear dye over it, helps with cleaning and color retention down the road...


FYI...the only place for brake fluid is the master cylinder
