To answer your question about Trim Adhesive:
My tube is old they now call it 3M 08001 Yellow Super Weatherstrip and Gasket Adhesive
http://www.amazon.com/3M-08001-Yell...p;ie=UTF8&qid=1332337891&sr=1-10Most auto parts store carry it. You want the nasty looking yellow stuff.
3M makes a whole line of similar products. For example, is also a spray called 3M 77, that does not dry. It's always sticky.
3M replied quickly. 5200 does not stick to HPDE, it just provides a gasket. The yellow gasket adhesive provides a mechanical bond. However they do list a adhesive that will bond to HDPE but, it will be a weak bond It has possibilities for fairing scratches and such. It is in the professional line so it will be expensive and hard to buy.
