Keep a little acetone close by when using spray foam. Dampen a rag with it to clean the foam of your hands even after it cures. Works on gorilla glue also.

And you have a good chance that your windows will not open and close nicely as the foam will actually bend the window sides in! Ron

I heard it's thinner though when it sprays. I may need the gun to dial it in as thin as I can get it regardless of the version I get.

Might just use the regular stuff w the gun.

You may be missing my point. The window and door stuff does not expand as much or with as much force as the regular and cures flexible instead of rock hard like the original. For doing your basement, you can use either and don't need the gun. Problem with the gun is that it is a PITA to clean AND requires a special cleaner. Spend ten bucks total and get a can of window and door and a can of original from Benny's or wherever. Try both and see what works best for you. If you put the great stuff around the perimeter first, you don't have to worry about getting into tiny cracks with the nozzle as it will bind to the foam board. Ron
