I bought an Interstate tank off eBay. I had
posted this in our "Things I've seen..." forum and only days later decided to take a leap at purchasing. The original price was too dear, but the seller sent out a lowered price to several lookers (my Watchlist?) and it comes with a fresh Ceandess gas cap so that's $75.00 right there. I offered a lowball figure against their offer and was instantly approved, so now it is mine. I use an outfit,
Metalworks, in Eugene, Oregon who acid dips tanks for $100.00, but until I get a good look at the inside of this tank I won't dip it - my fear is nothing would remain?! I have recovered several Roadster tanks and use the Caswell sealing system religiously but typically only when the weather is warmer and the viscosity and cure time is ideal.
My first Commando had a nice steel Interstate tank with Roadster side covers and I loved the look so will go in that direction. If anyone cares to PM me about any idiosyncrasies in dealing with these tanks please do! I am collecting data and since this is a long-term fix will apply what I learn to bringing this tank back to its duty.
