Good info Herm, thank you. figure I'll try some bondo and see how it goes. TroyHerm21 said:if you remove the plates you not only and end up with more space to fill but it'll leave holes where the plates were welded. Unless you carefully cut them out, but either way I don't see a reason to remove them. I bonded them without removal on my first tank, but i'm considering trying Quick Steel to fill 'em in on the one I'm doing now...
