Today's Aerosol's are crap

I can give PBlaster and SeaFoam Deep Creep as prime examples. Especially Deep Creep. It says RIGHT ON THE CAN "Even sprays upside down". HORSE HOCKEY! It will barely spray right side up sometimes. Really pisses me off because the stuff ain't cheap. I even called the company and THEY KNOW of the problem. I was told it "might" be resolved in the next YEAR.
