How to patch this???

[waterman28]

Any ideas on what and how to patch this? The body is made of plastic, polyethylene I think. there was some fiberglass patches on it but they were not stuck to the plastic very well and pulled right off. the plastic seems very slick. So I am hoping someone out there has had experience with repairing this type of plastic.
Thanks

The Sierra Trail Boss body is made of HDPE (poly) plastic and is very repairable. Fiberglass won't work at all on it. Try this:

Then use the search feature on the site and you'll come up with lots of great ideas. Good luck with it!

If its HDPE you should be able to plastic weld it. Harbor Freight sells plastic welders at a reasonable cost. I have a few cracks in mine as well but I think mine is made of high impact plastic. I tried welding it and it didn't work. I also tried the heat gun to remove oxidation and that didn't work either. I am curiouos to see what others say. My machine is a 1970 Argo.

With the epoxy, and also with plastic welding....the finished strength is dependant on how well you prep the surface.
When plastic welding you need to scrape the surface conamination off to give the weld good plastic to adhere to.
With the epoxy, the mfgr published adhesion strength with different surface prep methods....see thier web site.
Personally, whether welding or using epoxy, I'd fix the crack, then put another patch over the top of it for extra strength.

G/flex Epoxy Kayak Challenge - YouTube i had a six inch gash in the side of my max IV due to the primary clutch sliding over while it was spinning and cutting the tub. used this product over three years ago, and still have no problems with the repair. i used some small aluminum strips to hold the gash together on the inside, pop rivited on, then i put some metal window screen on the outside , and covered that with this product. worked great.
