Well, I decided to run up the credit card a little bit more. After doing some research into getting my fuel tank boiled out and sealed, I decided to just go ahead and tackle it myself. I just placed an order for POR-15's
Auto Fuel Tank Repair Kit, which wasn't bad at $55 (plus $10 S&H). They say there's enough product to clean/seal a 25-gallon tank, which is what my aux. tank is.
I did some calling around to track down a local radiator shop who could do this service for me, and after spending some time on the phone talking with the owner of one, I decided that this was something I could do myself. My tank is actually in darned good shape...no gum or varnish, just a little bit of very minor surface rust along the bottom. The guy at the radiator shop told me to just clean that out with muratic acid and flush it out with acetone (since it dries faster). But I was worried about how the acetone might affect the adhesion of the sealer, so after pondering this for a few days I just decided to go with the POR-15 kit, since I know they make quality products. Besides, it'll give me another opportunity to put together a "How I Dunnit" page for the website.
