If memory serves, you don’t even need to seal the pin holes… use tape over the holes on the outside and the coating fills the holes… I believe that is written on the outside of the can with the instructions…. a little does go along ways..

Richard, I wanted to seal the pin holes so the phosphoric acid would stay in the
tank long enough to clean the insides out! Only the little filler cap in the
corner to look into the tank, so no good way to inspect the sides of the
tank as a whole. I like the "idea" of un-soldering the top of the tank, but
not the potential for screwing it up!

I would lay off of the acid treatment, and preserve the steel that’s left. POR makes "Marine Clean" solvent that will clean the tank better than anything else, and will not eat up the metal. Redkote will seal up the remaining rust.

The existing solder joint looks good, I wouldn’t mess with it.

Tubs, thanks for the tips and video! Looks like your
tank turned out pretty nice.
I decided this morning to try to remove the top so
I can thoroughly inspect and clean out the inside.
I turned some 14 tpi threads on some 1" pipe to
screw into the filler cap hole, so I’d have a little
leverage to lift up on the cover. Am going to try
after a while, so wish me luck!
Thanks.

Tubs, your idea of blowing the liquid solder out with compressed air
worked great… Thanks!
I’m glad I opened it up, don’t think I’d ever get all that rust and crud out
otherwise.
Now, if I can sandblast the insides without warping the tin is the
next question. Will try tomorrow…… too many interruptions today.

Do you have a soda blaster? Less abrasive and less heat.

Most persons run their blasters at too high of a pressure thinking it is better..it is not…
