They are so minor, if I could get my hand in there. I'm looking
for a possible easy fix to smooth these out a bit. The bottom is beautiful, doesn't even need paint.   |

You'd need some PDR tools to push from inside the tank, I'd think.

(IMG:style_emoticons/default/confused24.gif) You could cut a small rectangle out of the bottom, fix the dent, and weld it closed. However, being that it is a vapor/gas overflow container... welding might not be the best idea. Others might be able to chime in. |

Maybe I should just fill it with some body filler. (IMG:style_emoticons/default/sad.gif) |

Most are dented or oil canned (thin metal).
I have thot about pressurizing them with air thinking that may sufficiently pop out the waves. Perhaps additionally persuading them with externally-applied heat or a roller. The fabricators may want to weld rods onto them pull them out, but that is delicate work on thin metal. |
