Poor Man's Foam Gun??

i have to say i have never had luck with any foam gun, now my cannon and PW, that worked great. but at harbor freight you can return anything with in 30 days for what ever the reason. if it doesnt work, take that ish back and get your money back. i have been doing that a lot lately, with this economy and fewer and fewer big details i cant afford to keep everything that doesnt work. besides my tool box was getting full of crap. i used to say, one day i'll use it for something and i never did. i went through my box and cleared out stuff from 7 years ago that still didnt work
