Ok several times now I have bought a pumpable garden sprayer, and it
works fine one year, but the next the pump action is all stiff and

Not sure if I can use a spray oil or not.

In the old days we used Neatsfoot oil on the leather pump cylinder
seals. Today some sort of plastic is probably used however.
