Gas Tank Cleaner?

[gruen911]

I had a gas tank in my 73T with a very small leak at the front seam. I tried having it fixed at a local radiator shop cheap. It came back and after a few hours starting leaking again. I then had a body shop who was replacing the front pan for me look at the tank as well to see if it was repairable. They said it wasn't repairable. I replaced it with a new tank.
I brought the old tank home and had it sitting on my rear balcony for a month under a few plastic bags. Finally I decided to have a look at it myself. I filled it with water and watched for the leak. After a few minutes I found the leak was coming from 3 very small pin sized holes. I got out the metal bristled sander bit and sanded all of the undercoating and surface rust away. I put some JB liquid weld on it and refilled it with water. No more leak. So now that the tank has water and most likley surface rust in it, what can I do and/or buy to clean the tank out myself in my garage rather than send it away to a local shop? Is there an off the shelf product that I can buy to do it with?
Any suggestions appreciated.

There is a product that is used to do motorcycle fuel tanks. It is called Kream. Most motorcycle carry it. The thing is that it is a three step process and the contents are in quart size bottels. At about $28.00 a kit I would hate to think how many kits it would to do a car fuel tank. I had my 25 gal fuel tank done by Renu for about $200.00 with dealer discount, well worth the money. The only trouble is that the outside of the tank was coated in the same black sealer. The Renu process also carries a warranty.

Actually, I have used the motorcycle kit and there is always leftover product so I think you can get away with one kit and an extra pint of sealer.

The first process is to clean the sludge out if the tank has been sitting with old gas. If not, go right to step 2 which is a rust neutralizer and etching process. Step 3 is the sealer which needs to go in and swirl around the inside. The coating doesn't need to be thick and actually shouldn't puddle anywhere inside the tank. I have leftovers of all three steps if you want, PM me.

Eastwood sells a kit for this as well. It contains the rust remover, metal etch (acid), and the sealer.
