Newbe with trim question.

I bet the tolerances are very close on there - the 3M tape will probably work but will also add too much material between the trim piece and the clips - you'll end up with a gap. They appear to be more of a rivet than a spot weld and repeating a rivet is going to be damn near impossible. You're going to want to clean it all up REALLY good and then try to find some type of "glue" to put in there - panel adhesive, epoxy, Gorilla glue??? I'm not sure what would do it - tough thing for sure. I will say this - the trim does look like it may come apart there, (2nd pic looks like there are two pieces wedged together) so maybe there is a way to get in behind them to redo those rivets...?????
