Just a thought... how come you guys don't make your tanks from stainless steel?,then you do not have to coat the in sides with any thing.
I have found there is not much cost difference in the price of the material , and you can not tell the difference when painted, and you don't have problems with rusting from condensation because of half fulling tanks. There is also the problems from rust when you solder , if you don't neualize the acid flux.
I believe the original tanks used a tin coated steel , that made soldering fittings really easy , and also stop the internal rust.. just my thoughts.
