Do you guys think it would harm anything to do a lap around the gas tank with duct tape or something of the sort? Just want to reinforce this patch with something because it seemed so easy to pop off the old patch.
I was actually able to pry the burr off with a scraper and pliers... was happy about that. Never heard of a rivnut before... interesting!!
re: getting rid of the burr:
Take a drill bit a couple-3 sizes larger than the hole, chuck it up in a drill.
Use medium speed, touch the drill to the hole. Dont let it grab or it will make things worse. The edge of the larger bit will deburr the hole.
Then I would pop a closed end rivnut in it with a bolt. Rtv/seal the shit out of it.
