Re: iron-on patch on a gas tank
Most glues will make some kind of physical bond, so whatever it is will need nubs to grab. Gorilla glue is that type. If the tank is smooth finish, it will peel right off. I've made molds before and they work because the surface is smooth, part comes right out. I've even used Gorilla glue in molds, which works great because it doesnt stick. Rough surface, glue sticks.
