I made some custom panels using speaker rings and fiberglass and body filler. I left most of the plastic panel intact, just modified the part where the speaker would fit in, and shaped it to have smooth curves and all that.
So the the piece is part stock plastic and part body filler. That's the final surface the vinyl was applied to.
I used DAP weldwood contact cement. I coated the piece and the vinyl backing heavily and let dry for at least 2 hours. I then pressed the vinyl to the piece.
In the heat of my car it has started to separate.
Did I not let the glue sit long enough before contact? I've read some let it sit for up to six hours. Should I try some 3M 80 spray instead?
About retrying it all... once i tear off the vinyl, how should i go about prepping the surface for another try? Sand off all the glue from the first run? Then maybe a 40 grit "rough up" sand before using the next glue?
