Hi .
i started molding my dash with fiberglass..
i stacked Spandex over it but not completely 100% covered with spandex
my question is. Does the fiberglass will stick on the OEM Vinyl (on not covered zone with spandex)?
if your glassing your dash you need to remove all the vinyl on the dash. if not you will just build up layers on top of it and it will not fit back in place right do to the extra thickness of the fiberglass
no it wont, and most likely the "spandex" will seperate from the vinyl top eventually
