thanks for the tips man, really appreciate it! i have a tank that i'm working some knee dents with, but i tried the 'ol cut both sides out and swap 'em trick. unfortunately, i didn't realize that my only means of welding, a flux core mig, was a terrible option as it is a porous weld and the tank material is very thin, making it super hard not to burn through. but i will definitely take your tips, your dents have such crisp edges, which i really want but haven't really seen anyone achieve with hammers. anyhow, back on topic, can't wait to see the new seat!
