Not all calk guns are created equal...
When I first started using a calk gun to put my flowers together instead of a tube of geii, I went to the cellar and grabbed one of dh's several guns that he keeps on a shelf. After making a bunch, my hand was a little sore but I figured that was the price of efficiency. Well I kept using the same calk gun until one day I couldn't find it. The only one I could find was a plastic one that I assumed was not as good.
Was I ever wrong! It is the best! With just a little pressure the calk comes out in a perfect bead, totally controlled and no pain in the hand. Its amazing and I will never use another.
It is yellow plastic tube holder with a black plastic handle and trigger. The words "Ergo Tech Series" and a patent number are on the black part and "Dripless" on the yellow part.
Beg borrow or buy one if you are a totem or plate flower maker and your current calk gun is hard on your hand. Dh isn't sure where he got it. His comment when I pointed out my discovery was "Oh yeah that's the good one."
Maybe Sherwin Wms he thought.
