Much of what I can do I learned by doing it including
removing dents from gas tanks. The tanks on the
motors I have repaired are mostly square. Simple
compared to your tank. Mostly curved but still flat on
top. And then there are those straight lines. Yikes!
That’s quite an accomplishment for your first attempt.
You done good.
