Immediately after applying the epoxy to the backer you can insert it in the hole and pull it up until it is tight with the original panel and slide the retainer clip over the pin until it touches the metal and firmly holds the backer in place. Mix the epoxy and apply it to the front side of the backer and the center pin. Best deal on goodyear air hose check this out https amzn to 3b5cjvy how to fix a hole without welding no warping.

The most permanent repair to a hole in sheet metal is to weld the hole shut. Any kind of welder can be used but the best results come from a competent repairman using a tig or mig welding machine.

The complexity of welding increases as the thickness of the material decreases. I ve read that works for welding shut drilled holes. Try welding with a scrap sheet metal piece and practice many times until you start working on more important projects. I have no experience with mig other than reading various forums.
