i just redid my door panel insert. the panel with the arm rest on it. i redid them in some nice material and really happy with the way they came out. now to my question, what do you guys recommend for me to put the inserts back in. they use to have the factory plastic heated rivits... it looks like im gonna need some glue but whats gonna make them strong and look factory again??

 

no ideas on what i can use to put them back together??? ..... glue , fiberglass, exc....
