Review on （Black）Professional Expanding Caulking Application Applicator by Warrick Dembo

The gun works well. I wish I had a longer barreled gun but bought this for budget reasons. PLASTIC TIPS are free. They, or at least the threaded base, must be made of hard plastic or metal. If you try to attach the tips to the barrel of a gun to keep them from loosening, they'll easily loosen and keep spinning with no added value. I'll try wrapping tape or duct tape around the top of the trunk next time I use it to patch up contractor mistakes in my attic. Tip: turn on all the lights in the house, go to the attic with a small flashlight to maneuver. You will see gaps around light fixtures, ceiling fans, etc. You will also find gaps in drilled holes for cable routing. ALL of these gaps MUST be filled in order to achieve the best home efficiency. Great Stuff spray foam for gaps and cracks from Lowe's or Home Depot. They also produce foam for windows and doors. I will remove the skin to randomly inspect windows and doors that require spray foam.
