I would scrap it. As you said part of it is going to be old paste. All manufacturers don't recommend mixing old with new paste because you change the rheology of the paste.

Passives are at least fairly simple, generally either they solder or they don't, testing with paste stenciled on to glass slides is one variation and a hot solder dip is another. The glass slide is nice because it's closer to the end use scenario.
