Summary: Five tubes and I hardly spilled any!
Comment: I hate squeezing a caulking gun. The pain in my wrist makes my hands wobble and a bad job just gets worse. Needless to say I was pleased to discover that Wagner had a cordless gun on the market. A friend at the marina where I work on my antique cruiser had purchased one and recommended it.I purchased one on the Internet and ten days later it arrived. My task involved scraping the bottom, then raking the cotton seam caulking out of several planks on my 30' mahogany sedan cruiser, then re-caulking with cotton. Two days of this and I was ready to seal the bottom with butyll on the cottoned seams, and good old roofing tar on the others.
Butyll is very hard to squeeze out of a tube, and I had to make four, flawless, continuous, 30' beads while lying on my back in the mud. The Wagner did the job much more effectively than a hand gun.
The roofing tar went onto the upper seams (keeping well clear of the white topsides). It squeezes out as the planks soak up and compensates for the increasing pressure. It went on really easily, though there were many seams to do.
The first charge ran out after three tubes. The butyll was very thick, though. I was impressed that the Wagner had the power to squirt it at all.
The rest of the tar went on without another charge, so I don't know how many tubes of normal viscosity the batteries can manage.
Five would be a good guess, I'd think. The charge takes three hours, by the way.
Two of us have these machines. What we'd really like is access to extra battery packs in case the Wagners play out before we do.
All in all, I found the cordless caulking gun an excellent addition to my toolbox. It is definitely not a toy.
