Does anyone know what type of primer/prep the body shop needs to apply before painting the OEM rubber 90-93 spoiler ? I want the paint to stick...the OEM rubber is good on the one I have...but I'm unsure of how it will hold up in the hot sun after its painted. Does the aging rubber of the OEM spoiler make repainting unpractical...even if its in good condition (except for the current dull paint finish) ?
