Hey guys. Got what probably is a dumb question. My 2006 gto I bought back in October I just got out and I was wondering what the gummy sticky stuff they use is called to hold the bezel around my double din radio. It was in the car already. But it looks to have melted and ran down the trim parts and now has left stains over time. I've tried magic eraser and no luck. I'm assuming it won't ever come out... is it buetle they use? Thanks.
