I have some carbon fiber look vinyl for the interior of my roof and doors. I tried 3m spray adhesive to adhere the vinyl to the aluminum and once the sun hit it, and it got hot, it began to sag. My friend suggested gorilla glue. It worked, but was messy and left lumps after it dried, not smooth. I'm not totally happy with it. Is there a better product out there that you have used for this application?
