Title: Does what it does quite well
Review: I bought one of these from Grainger. I lengthened the air hose using same size fuel hose, and had to put a needle valve in the air line on the gun for better control of air flow. With those changes the thing works great. Lays down an even bead. I use an add-on caulking tip with a 1/8 inch hole. With this gun I can lay a bead down that you can't see to cover baseboard-to-wall and door frame cracks. Different caulks will push out very differently so you need fine air pressure and flow control. I use about 5 psi air pressure and the needle valve open only a small amount to lay down Polyseamseal All-purpose caulk, which is quite soft. An on-unit air regulator and 10 ft hose sure would enhance it's ease of use. Taking all things into account, I'm glad I got it.
