Anyone with some good used/inexpensive gas tanks within a reasonable drive from central North Carolina?
The ones out of the 78 Royale seem fine as far as integrity, but have a very dense layer of crud. I have tried some soaking and sloshing with water and TSP, one attempt at a gallon of acetone. The area in the middle where I can physically get to it are cleaning up fine, but two baffles prevent direct access to outer third on each side. Local radiator shop guy said he would do them, when I got there he said the smell was so strong he wouldn't mess with them. One guy in another town said he would do them, still several hundred dollars each, and you never know how good they do them.
I'm thinking of building a big rotisserie type thing and putting in some nuts, bolts and chain. If I could turn the whole thing at different angles I think I would be fine...
ideas or ready to go tanks are welcome!

Hmm. Spend hours of your life to save pennies. I have done a bunch of that
in my life, but, the older I get, the less I feel like it makes sense.
Small amounts of solvents are ineffective at dealing with tank varnish.
Your shaker concept will work, properly applied. Strangely enough, so will
alcohol blended gasoline. That sludge, when loosened up, will plug up a
WHOLE BUNCH of downstream filters, so be prepared with lots of spares.
Varnish is easier to prevent than it is to deal with after it forms. Guess
it comes down to, what your time is worth vs someone else's who is skilled
at varnish removal.

finding good used tanks are a matter of luck... finding used tanks is one thing, finding clean one's is another. But they are out there, and sometimes can come with a whole parts coach attached.
The DIY method would be vinegar in my opinion. just have to either coat the tanks afterwards, do not clean the rust out and let the tanks sit open for any time, they will re-rust worse then when you started.
there is no cheap and easy way. I have seen plenty of methods, and stories of success and failure. Radiator shops seem to be a good answer, and there are other places that deal just in gas tanks. Depends where you live and what is around you. Some places will cut open, clean and re-weld the tops of the tanks as well.
worst case is your other answer:

I took mine to an automotive rust stripper. The kind that does fenders, body panels etc. Charged me about a $100ea. Did a great job. I also removed the straps so the tank would get cleaned everywhere. I have a spare I'm still trying to get all the hardware out of it. Didn't clean up very well either.

Tyler,
I have a pair in Houston, please advise:
1) How much you want to pay for the tanks
2) How much you want to spend to ship them?
