Anyone who uses this knows how unforgiving this stuff is if you get it on places you don't want it, like your clothing. To lessen your odds of keeping clean, they thought of this nice trigger that screws onto the top, that constantly unscrews itself while using it. Then the foam starts shooting out the base of the nozzle all over your hands, floor and clothing. Most of the time I use this I don't have the luxury of keeping the can away from my body. I'm usually on my back shooting up in cracks or whatever. Please redesign this so the damn trigger stays put.
