Just for reference: Under the paint, it'll probably be a semi-brushed finish, with swirls and such instead of a straight brush pattern, so you probably won't have to do anything to the finish unless you want to.

Anodizing is outside my area of expertise so I can't be of much help. It seems that, once upon a time, tanks with dyed anodized finishes could be purchased but I haven't seen them in ages (and I do visuals on maybe 1000 tanks a year), so there may have been a problem (as there was with the experiments linings, etc.) You might try contacting Luxfer or Catalina and see what they have to say about the process...or FredT on this board - more or less the resident guru when it comes to things made out of metal.loki00:But the problem with aluminum is in the unsealed state, it oxidizes. That's why I was wondering about the ano. It seals the finish, and toughens it against abrasives.

teknitroxdiver:Oxidizing isn't a problem on the outside of aluminum tanks, it's a self-arresting process, and without paint on it it's even less likely to pit (pits are what get tanks condemned). No anodizing or anything at all needed.
Personally, unless you have easy access to a shop, I'd dump the tank. With a shop, I'd finish the strip job, shot blast for appearance, have the tank hydro-tested and call it a day. Nothing wrong with an aluminum colored tank.
