Spray cans are very frustrating for those of us with weak fingers. Mine have gotten to the point where i needed two hands — one to hold the can, the other to push on the button with my thumb! Try painting that way, or spraying oil into a skillet, spray starch onto a shirt, or lysol onto a countertop. Then I discovered the device shown here. It works for me, and that’s really saying something! I bought mine on Amazon. In fact, I buy almost everything there. Saves time, saves money, and I can’t drive to the store anyway.
