5A few usage tricks
By HMMWV
This gun has alot of torque and will dispense thick adhesives like liquid nails quickly and evenly without the jaggies of a typical manual caulking gun - you get one nice continuous bead. To keep panel to panel consistency, I glued a cheap countdown stopwatch on the back of mine so that I could dispense a known amount of material, i.e. 8 seconds worth on a 4x4' panel, 16 seconds for a 4x8 panel - basically when doing repeated work you get excellent repeatable results and can go through material rapidly saving alot of time and sore hands from manual caulking guns. If your stopwatch works as a count-down and up modes, you can time your first panel, then set that time for each additional panel.For thin material such as latex caulks I advise a very small opening in the tube - the dispensing rate is so fast that the thin hole you make is all that holds back the dewalt from squirting the whole tube out. Since the thin material comes out at high pressure due to the small nozzle, it expands in width afterwards and makes a wider bead than initally dispensed, so downsize the guides on the plastic tips about 2 sizes and you will get close your desired width. If you have never used a particular caulk before, start by just snipping off the very end of the plastic then cut back more if needed. It's easier to snip off a little more of the tip if it's too small but you can't cut it smaller if its too large to begin with! In my kit I keep a pair of wire cutters to snip the end of the tubes wider or at a sharp angle.One fully charged XRP battery can empty 40+ tubes of liquid nails with power left over. It's a better tool for adhesives than caulks just due to the viscosity difference, but with practice it can force caulk into small gaps with ease. Re-caulking a bathtub can be done in a single trigger squeeze leaving a professional finish.

4good heavy duty gun
By W. A. Speirs
Well made heavy duty caulk gun. Not for standard caulking jobs however. Too costly, too heavy, and unnecessary for typical jobs. Great when you have a lot of caulking to do or with high viscosity caulks.

5Dewalt is king!!
By mow224
Dewalt has done it again. They make the best cordless tools! The caulking gun works great. Love the speed dial to control flow. The only complaint is over priced for bare tool, but glad I spent the money.
