Hey folks, afraid I haven't been very active on the site lately (or at the campground either :(), but wanted to pass along this tip.
Had to repair the windshield washer reservoir on the 1500 HD recently. It is made of high-density polyethylene (HDPE), a plasitc that is notoriously difficullt to bond to.
Researching the issue I found, 1) an epoxy formulated to bond to difficult materials: G-Flex and 2) a surface prep for HDPE: Flame Treatment
After practicing on a few samples cut from a milk jug, I solvent wiped, abraded and flame treated the cracked area (after stop drilling as suggested above) and reinforced the repair with a strip of cloth. Got a very good bond strength.
This will work on all HDPE objects I'd guess, which in our campers is a common material. For the tote, I'd reinforce with fiberglass.
Good luck with it.
