I bought a Wolfgang Foam Gun awhile ago and it works ok...I found this in the Lee Valley catalog this weekend http://www.leevalley.com/en/garden/page.aspx?p=70816&cat=2,42194,40727.... I live in a condo and having and power washer and foam lance doesn't really work... Now the silly question.....Would a 2 gal garden sprayer and wand not work for foam?...Just wondering. Your opinion? Thanks
