Hi! This is probably not where it should be posted. I am taken advantage of this nice weather doing some work on a cub and equipment getting ready for summer. I am having trouble with aerosol cans they stop working before all the fluid is gone. some half some more than half left. Kroil, wd 40, paint same thing. This is not new problem for me . I just don't know why they stop working. any ideas? Thanks! Tom
