John ... LOL!
I know what it won't stick to ... any flat surface you are applying too over 3/4" wide. It will stick to any body part (hair included) and any piece of clothing with great tenacity ... I just ordered a pack of these nozzles ... :)
I looked at the guns and other devices offered by the spray foam companies and they are all $60-$70 for manual ... and the per can price I believ jumps to $11 each.
I plan on applying to my Guidesman Blind walls this summer ... will hopefully post success stories ... :D
