Welcome to the forum
Hmm, not a bad idea at all, thx. I think I may need more than what I could shave off though.......You may call me insane, but take some shavings from thick solid areas like the mounting tabs and use it... same stuff...
It's a type polyethylene - HDPE (high density polyethylene) or XLPE (high density cross linked polyethylene)
There is no externally applied adhesive (Epoxy, JB Weld or super glue) that offers a permanent repair and an internally applied sealant is primarily for steel tanks. Plastic welding is a temporary fix also as the polyethylene tank has become brittle from exposure to ethanol and or gasoline. The only long term temporary fix is a new tank or replacement with a used tank.
The black plastic tanks may be ABS or polyethylene. ABS is generally less flexible and a bit more brittle than polyethylene. Plastic welding is a better fix, but on a 10 year old vehicle (especially of Chinese manufacture) the best fix is a different tank.
thank you. I don't think I can do the plastic weld as there is a patch of unknown epoxy material on top of it. will look for another tank
