I have all four of my cocktail shakers out of my 68 bird convert and beadblasted them. These aren't rusty or pitted at all. One of the front shakers appears to be slightly leaking at each of the spot welded mounting brackets / feet (all of them). It's just enough that you can see wet stains around the feet. I sprayed the shaker clean with carb cleaner, but the wet stains came back after sitting for a while.

I noticed that the spot welds are much deeper than on the other shakers, so perhaps that is causing the issue. I'm open for ideas as to how to fix this. I really don't want to drill out all of the spot welds and pull the legs off with re-welding them unless I absolutely have to. I'm thinking that I could perhaps drain them, flush them out with carb cleaner and then seal them with something, but I'm not sure what to use. There are suspended weights inside supposedly and I don't want the weights to get stuck in place. I'm thinking that the weights are probably heavy enough that I could just use something like ordinary rustoleum and it wouldn't impinge on the movement of the weights, but it would also need to be unaffected by the oil inside. If it's hydraulic fluid in there, it would be a problem. I have no idea what kind of oil is inside. I'm open for ideas.
