How do you reccomend attaching a trim piece that came off? I'm talking about the notorious small piece right below the fuel door. What do you guys use that works?

 

You could use really any type of apoxy really just be careful that it doesn't come out from underneath. Or you could even use an extra strength outdoor silicone. Once its on there it won't come off without a fight. Or the other alternative is get rid of all the strips all the way around.

 

Are you talking about the rubber molding? If so, take off the old tape and then go and get yourself some new tape and attach it to the molding and make sure all the residue is off of the body before re-attaching.

 

3M double sided tape would be best for that trim piece and theres no excess glue to clean up...
