Using your Convoy® RS caulk gun is a breeze. First, insert the caulk tube into the barrel. The extra-long barrel makes this process quick and easy. Then, use the extra-long seal puncture pin to open the tube. Hold the gun with the contoured grip on the 360-degree rotating handle, which allows you to work in any position, even in tight spaces. Squeeze the trigger, and thanks to the Enhanced SST feature, you'll get 20% more thrust force without extra effort. This gun is great for thick materials. When you're done, clean the gun to keep it in good condition. Simply wipe off any excess caulk and store it in a dry place. Avoid using it with materials that are too hard for the gun to handle, as this could damage the thrust system.
