Not sure about how to improve the cosmetics of the soldering itself, but as long as you thoroughly clean the joints to remove any remaining flux residue and then use a good self-etching primer, painting over the solder should be no problem. NIce piece of work.

I don’t have any self etching primer, but I do have some phosphoric acid…….
perhaps that will work?Prepare to be boarded!
Just guessing here, but when I watched the guys “sweat” solder pipes, the wipe off the excess solder with a wet rag while still somewhat liquid…
So guessing warm it up until you can “wipe” off the excess
I had a can of water and rag ready with the idea wiping the excess solder off,
and maybe it would have worked if I had three arms or another person.
Then again, don’t know if it would be good to keep quenching the hot, thin, tin.
Not sure if it would cause buckles.Buc, for wiping the solder joints you need a DRY cloth that is 100% cotton, old blue jean material is good. no synthetic material or content in the cloth. I would try this, using your propane torch, move along the seam and quickly follow with the dry cloth. Do a little at time , leaving the seam to harden behind as you move along, so that the whole seam doesn’t come apart.

Joe, I thought about doing as you suggested last night, but chicken out for the reason
you mention……. didn’t want to go one step forward, and two back!Therefore, I got out the 5″ sanding disc and drill and some Roloc? pads for the
tighter spaces. The 80 grit disc made pretty fast work, plus cleaned and prepped the metal
for painting.Next I’m going to fill it up with water and check for leaks, and more than likely, will find some.
I couldn’t remember how finely finished the original soldering was done, so I found a couple
of photos before I took it apart. Presume my uncle put that brown laquer primer on it years ago,
just to preserve the tank a little.
Prepare to be boarded!
