any special trick to remove a large bump 2X3 inches on a top corner … the round edge is pushed in may be an inch or so…. a nasty bump to say the least
the tank looks real good except for that nasty corner bump
I have seen utubes fixing car surface bumps using heat and cold to pop out a bump. the bump perimeter is heated up and center cooled fast to contract the metal and pop the bump outwards
I see those suction cup dent removers advertised, but they may only work on todays light gauge automobiles, or maybe they’re useless. Pressure tanks are pretty rugged . I usually assume that most major dents happen when someone drops a full tank on the ground.
