Tank Rust? Any concensus on best fix?

Used 'electro-rust' removal, need help gettin pics up!

Like I said, my tank did not have pin holes, just 13 years of water condensation inside an empty tank parked in a drafty garage. I have pictures of the process and I have saved the rust that went into solution (most of it) as a result of the electrolysis method. The pictures are in an album on the computer I use for the internet. I took pics of rust removal from both the main and the reserve tank. Now I see the icon of the mountain. lets see if I can pick up a picture from the 50 or so I have in the album.:smile:

 

Gittin' the rust out!

I want you guys to know that the electrolytic method of removing rust is fantastic. I can see doing what I have learned to do here on everything else that I have that is rusted.

If any of you want to try this I recommend you read a web site named

the pics are great and the write up comprehensive and humorous.

I had a lot of trouble locating "washing soda". Turns out that it is the same thing as "soda ash" (the stuff used to boost ph in a swimming pool) I bought 2 lbs of it for $6.00 at my local pool supply store. You probably don't have those in the mid west. So, make your own. Buy a box of Arm and Hammer Baking Soda (Bicarbonate of Soda). Spread it around on a cookie sheet and cook it in the oven at 300F for 2 hours and you will have "washing soda" or sodium carbonate or "Soda Ash". Get it??? Read what the old guy writes about it in the web site I gave you above. The filler neck rust is what the entire inside of my gas tank looked like after I filled it with and then drained it of gas while trying to get it to start after the carbs were rebuilt.

Well I may have attached one pic, but how do I attach more?

 

I think one of the reasons its hard to get is because it can be used to make a bomb!!

Go figure why its easily obtainable here!

 

I used Evapo-rust, it was easy, my tank just had a lite film of brown and came out like new. I've put 2K miles since the restoration it has run flawless so I must have got it all. I don't know if it would damage paint because I had stripped the outside of the tank first.
