Tubs, I’ll have to give the “glue” method a try for pulling dents sometimes.
I’m surprised it even sticks good enough to pull dents.
I went to the big city today to look for the 95% (Tin) / 5% (Antimony” solder
as mentioned in the article. The closest I could find was some 95% Tin, and 5%
silver, sold for “Hobbiest and Jewelers”.
I tinned the three dent areas on one back corner of the tank, using the
alumi-weld rods, then used a little bottle gas torch to heat of the dents
and melt the solder in. The dents, being on a rounded corner of the tank,
was the first challenge. Filling in a dent on a flat are would have been easier.
It seem like the solder I bought was a little hard to get to flow how I wanted it.
The solder did seem to adhere okay to the pre-tinned areas though, and not
at all to the bare aluminum.
The solder was plenty hard when filing and sanding. I ended up using a sanding
disc in the drill to level it out, then sanding with a board.
The area I repaired kind of looked like a bad Bondo job, except using solder.
Perhaps practice, the correct solder, and more patience would help!
The solder I used. I only found some “previously owned” solder on EBay that
had the 5% Antimony. ……. not sure if they make the correct stuff or not,
will have to look some more.

I tried filling in some of the tiny pits on the repair areas, using the same
solder, and my electric soldering gun, with limited success.
Prepare to be boarded!
