No back ache or up and down on your knees. Fast,
While the Albion spot pro definitely saves your back cleaning is difficult as with any silicones. It did what I wanted without the backache in 1/3 the time. Worth the expense even if itâs never used again. Great product.

super tool!!
I fabricated another handle off those two slots on the other side of handle. This really helps in aiming it to the screw head. Wonderful tool and so simple to use. The cost of this bulk loading gun will pay for itself. I own a small mini storage complex….

Good idea but design issues
We have about 5000 square feet of metal roof that we wanted to seal the screws on. This caulking gun may have saved a time and reduced material quantity used, but it was not as easy as the videos suggest. Trying various things and a few modifications helped.The biggest issue might be flow – a lack of it. First of all, some screws that don’t project very far above the metal won’t depress the movable disc and spring behind it. I ended up drilling a small hole through the disc and adding a metal screw that projected out about 1/8″ – that helped a lot to let the caulking out.Another issue is that the spring is retained in the barrel by a metal disc above the spring with just small spaces at the edges. This restricts flow of the caulking a lot. A washer with a hole in the middle would let a lot more material past the spring and through to the end of the tool, reducing the pressure required to operate the gun. Even with gloves on, the pressure required soon caused a large blister in my palm. When I use it again, I plan to try a washer in place of the solid disc to retain the spring.It takes a lot of down force to operate this gun with the screw attachment. I ended up making a side handle to help with this.The plastic parts also concerned me. While the gun did not break – yet, metal could be a lot better.Another suggestion – the gun slides easily when put down on a roof. If it slides off, this creates a hazard for anyone below the roof and a fall could destroy the gun. I used a foot long piece of foam pipe insulation over the gun barrel, taped in with electrical tape. This helped make the work safer.Direction on what type of caulking to use would be useful. Silicone does not last that long on a metal roof, so we wanted to use something more durable. Someone suggested using Gutter Seal. Don’t. It’s too thick and sticky. We settled on a urethane caulking, which comes in a variety of colors and flows better. We hope it lasts.

Missing/Inaccurate parts
The extended nozzle was not included as indicated on the item page. The end cap was black plastic. The one in the photo appears chrome/stainless metal.
