Did the search (even advanced!) - didn't get suitable results apart from lot of discussion about repairing cladding scratches/color.

Here's a bit different story:
cladding is sort of falling off, if you can say so, in two particular places:
1. driver side upper corner of hood insert is sort of bending up, and
2. rear door left corner at the left rear lamp is torn off. It seems this has been started because of reckless opening of rear door - now I have to press the cladding to metal w my left hand always when I open rear door...

Any suggestions on what would b the best approach to fix these two?

I guess heating w paint blower, and sticking w something afterwards would b right steps to star with.
But - what kind of glue (or gluing material) could I use? What could b pitfalls? Is cladding material heat-fixable, so to say?

Any experiences?

Thanx in advance, folks!
