Gas Tank Cleaning- The Lazy Way

After fighting a tank which sat for 30 years full of gas, I resorted to outside help!
Here's what I tried so far:
Hand shaking with nuts and bolts
Attaching tank with bolts inside to side of riding mower wheel with bungee cords, jacking up mower wheel and running
dunking in parts washer at local motorcycle shop
electrolysis
I hate to admit defeat, but just got tired of it, so I took it to my local radiator shop and asked them if they could do anything with it.
They said they didn't think so, but they would try, and if it didn't work they wouldn't charge me.
Here's the result.....should have done this first!

Forgot to add ...cost was $30.00, for dipping, steam cleaning the inside and coating inside with wd-40
When I asked what kind of acid they used, he said he didn't know but it was a white powder he mixed up?

Looks great. Well worth the $30. Not gonna coat it?

No coating planned.
I've seen too many failures with Kreem.
I've heard good things about the POR, but don't trust myself enough to do it correctly.
I figure if I keep fresh gas in it its not necessary.
The tanks come from the factory without a coating so I figure it's overkill anyway.
I've been using a rusty tank for a couple of years now with no problems.
I added an extra inline filter just in case, but haven't seen anything get into the carb at all (or the clear filter either for that matter).

Cool, I used the POR-15 liner. That stuff is great, and it's the easiest part of the whole process. The must be careful to fully plug the length of the crossover tube.
