1998 chevy S10 needs help with trim

[SooZen]

Hi all, I am new to your forums which I found when researching my problem with "Blanca", my '98 Chevy S10 (she was a Mother's Day gift from my boys back in '98) She has been truly reliable and gets me to my arts and crafts venues (I am an artist) and home again without fail.

Now she needs some help. The soft sided trim on both sides is coming unglued and I would like to know what product and what to do to fix her. I am a devoted Chevy girl (lifelong) and don't want to see her looking ugly. She and I would most appreciate any help or resource or for re gluing the trim. I tried Goop which I use for my art but it only worked for one year and now the peeling off is worse than before. Thanks!!!
