I know this should probably not be on the forum but I have seen other ATV related posts. I got a nice size hole in my tank for running over a tree while it was getting dark. I am going to try to repair it myself. I didn't know if anyone has done some plastic repair themselves and could recommend a kit to use. My uncle tried to epoxy over it after adding a piece of metal(like a big washer for a screw) and it still leaks.
I was going to try to use this(I would rather not order something online but pick it up locally if lowes or something has it):
I watched a video where someone cut a piece of plastic 5 gallon bucket to a general size of the hole, Heated the plastic of the bucket with a blowtorch for welding and heated the hole almost to melting point then fitted the plastic into the hole so they were melted together. I would then sand down the rough area of the plastic and epoxy where the "plastic weld" would be to hopefully create a good seal. Any ideas on this?
