Good luck dude...

Make sure you have good, clean joints and welds... when you're done, put some water in the tank and attach a pressure hose to "pressure test" it and make sure there are no "pinhole" leaks... if so, fix them, if not, empty the tank, dry it, finish the metal, etc. Once fab is complete you can creme the tank with a sealant. You can get tank creme in a lot of "automotive" places.

Finally, do your paint and final finish...

Hope that gives you some insight. There's an old book I have called Metal Fabricator's Handbook that has good info on building tanks.
