HELLO To repair the polyethelene containers go to the nearby farm store and get a plastic welding kit ( it uses hot air and a plastic welding filler rod). All the farm tanks are made of this material and nothing seems to stick to it, believe me Ive tried epoxy, esters, caulks, and solvent welding,,, then I asked at the farm store where they sell those tanks for water and fertilizer and such and they showed me this kit to use. Hope this helps Al Boehm
