I had a dual nozzle Fog Buster that sat on the shelf for 7 (yes seven) years after I bought my PCNC 1100.
I finally gave up and sold it last month and guess what came in the day after it left. You got it, a job that the Fog Buster would have worked beautifully on.
Oh well, at least Fog Buster is made about 2 miles from where I live.
