I've heard good on Preval over the years & the price ($16) is dirt cheap. the only thing I could see going wrong is improper surface prep/contamination in your mixing steps/moisture in the hose. EDIT I Googled it & it has its own pressurized cans of propellent so that elims the air hose potential issue
