I haven't used them, but there is a "button" on the bottom of the can that when pushed breaks a seal on a chamber inside the can releasing part 2 of the paint into the part 1 of the paint. So the whole can is now activated, just as it would be in a conventional gun. I have never been sold on the idea that you can get as good of paint out of a spray bomb as you can from a gun. It's usually lots thinner so it can be pushed out of that small nozzle.



Thats what I was thinking--some method of activating the whole can. Makes sense.
This method makes even more sense for colors. Small projects. odd colors etc.
I wonder what the safety people think. Catalyzed paints are far more dangerous...that is IF they use the 'normal' isocyanate hardeners, which these may very well not!
