I once saw an article that suggested using oil to keep the oxide from
re-forming long enough to make the solder joint. Unfortunately, I can't
recall where I saw the article. Probably in QST sometime in the last 15 to
20 years [guess that really narrows it down, hi hi]. I've never tried it.
I do remember seeing a vendor at a hamfest selling "welding" rods that would
allow you to weld aluminum with a propane torch.
