Hi Mr. Earl, Thanks for the great advice. Ironically, I dropped my tank off today at Gas Tank Renu Ltd. They specialize in gas tank restorations. Initally, they suggested sandblasting, installing a liner and possibly fibre glassing the exterior. When they saw the tank (exterior looks like new - and I want to keep it original), we agreed that they would start with a good cleaning and put a liner in the tank if needed. The only problem with this liner solution is that a drill hole is necessary to allow the excess "liner/sealer solution" to drain. I was hesitant to agree to an additional drill hole but, when I saw the other antique tanks at the shop and was shown the entire process, it made sense. Has anyone done a similar restoration? I was told today that they have a better idea of the internal rust damage following the intial cleaning. I could definitely hear metal rattling around inside. Look forward to any further thoughts on the subject. p.s. The chain is a great idea.....Less stressful on the tank than sandblasting.
