I have tried many types of caulking guns. Cheap ones not so cheap ones and many in between. Many of which you will find in my paddock where they were chucked out of frustration.
But no more I cry for I am now the proud owner of an Air caulking gun.
No moving parts. Nothing to bend or break. Just hook up the air, pop in a tube of your favourite goo and away you go. As you will see in this short video.
For $80 AUD it is a no brainier really.
