Saving Gas Tank

If you can't get Acetone, then I am guessing meka is out of the question.

Do you not have home depot down there?

Home Depot left my country a few years ago..
This tank is the one on the left side, I still have to start cleaning the one on the right side, I think it is in a similar situation since I can put my hand through the mouth and I can find the same material at the bottom...

Yesterday i continued with the cleaning of the tank
Luckily only surface rust
Then pass a phosphatizing deoxidizing liquid

That's some work. I once did a Jeep gas tank. I used hot Pinesol (wood floor cleaner) to dissolve the gunk. But it revealed pin holes in the bottom of the tank. As the tank was dented from the Jeep being back into a stump or similar I opted to cut open the tank, reshape and patch in new metal. Still near boiling PineSol worked really, really well. I used it on a carburetor as well.

yesterday I continued with the work on the gas tank
I turned to the advice of several friends, all amateurs, so I hope that this way of doing it will give good results.
The plate was screwed to better support the weight of the 42 gallons, and it was welded with plumbing tin. It still remains to seal the head of some screws and do the leak test.

You made me think on a Monday morning - and that is not a good thing. I asked myself what is the active ingredient, and found the following. The Pine Oil gives the product its pleasant 'it must be working' aroma, but the active ingredient is glycolic acid.

I used plumbers solder on my tank as well. After several false starts due to pinholes I eventually got it sealed up. It appears to have been holding fine for a couple of years now.
