I use it to install doors and windows and seal buildings and it works great, the bracket on the end of the gun holds the adapters (which are included) to fill in hard to reach places, one is like a regular foam spray tube and the other is about 2 inches long and the tip can go into 1/8 inch cracks. It's well built and easy to use. I recommend reading the care instructions as most problems people have with spray guns stem from not cleaning them properly.
