What is the best adhesive for...
 

bonding the trim (1/2 inch molding trim) to the quarter panel?

What do you guys use that works well?

The little trim molding piece glue has come loose and I want to prep and reglue.

Thanks

3M double stick tape ....the stuff works amazing and its all your molding and decals on any car now a days is held on with pretty much...you can find it at like any hardwear store or go to a autobody shop and see if they would sell ya a roll (never know unless you ask)
