But if you do decide to seal it DO NOT use Cream tank sealer or any other sealers unless you want to have to clean it out and reseal. I have used Caswell's epoxy tank seal on many tanks and have had nothing but excellent results. It will seal pin holes, split seams and rust holes to a certain degree. caswellplating.com. Get your tank up to the point of painting before sealing.
