Worked great. Used for windshield adhesive. Adhesive came out with a nice bead and no effort. Not bad for the price.
UPGRADE to five stars. This tool will lay a perfect bead for as long as I can hold the trigger or until the caulk runs out, whichever comes first. Applying caulk used to be a major job. Now the major job is preparation. Caulking itself takes minutes. I ran through six tubes of caulk in one use easily. I'm caulking the joint/gap between the floor and the wall throughout the house, per the weatherizing advice of my local utility company. It's a big job. Without the air gun, I couldn't do any of it.
It took some time to find my way around the tool. i learned by making mistakes and by picking up information others shared in reviews. For my fellow inexperienced users:
1) This air-powered caulk gun came with no instructions. Granted, it's a caulk gun. But it hooks up to an air compressor. Its wonky trigger works best if you ignore the smooth, shiny, finger-ready curve and squeeze it from the underside.
2) The connector hole on the gun is threaded and empty. Buy a male connector at Lowe's (unless you have a male connector at the tool end of your hose). Screw it in. Snap its nose into the hose's female quick-connector.
3) The hose is 3/8" (internal diameter); air leaves it and enters connected devices through 1/4" NPT inlets [NPT = National Pipe Thread Taper]. This is standard.
4) Wrap the threads on the black base of the caulk-tube holder with Teflon tape to prevent air leaks.
5) A secondary pressure gauge and regulator, connected between the hose and the caulk gun, gives you more control over caulk speed and bead size. Screw a male connector into the hose side of the regulator, a female into the gun side, and snap in place. I bought the Bostitch BTFP72326 Regulator and Gauge Kit with 1/4-Inch NPT Thread. It works great.
6) Work out the settings for the bead you want on a piece of paper or cardboard before you start caulking for real. Start with 40 psi leaving the compressor and 20 psi going into the gun.
7) Make sure your caulk is fresh. If it's immovable, the air escapes around the tube. An unopened tube doesn't guarantee fresh caulk.
Saves on hand cramping. Just wish the trigger design gave you more room for your fingers.
It works however use the lowest pressure you can
worked as stated.
