Step 10: Pump it Up!
Pump it up until the gauge reads about 35-40 PSI. You probably shouldn't pressurize it more than 50 PSI.
Check for leaks. If there are any, it might work if you seal it up with more PL Premium (I don't know for sure if this will help) and let it dry.
Detach the air-osol can. (Yay, you can finally call it that!)
Spray to your heart's content (or until the air runs out)!!
