I for one understand your frustration Greg. It is annoying to use a cheap caulking gun especially when you are trying to apply a smooth bead of caulk to address some air leakage in a window long after the finish trim has been applied. To get lumps, surges and air pockets is very irritating to say the least. I'm glad you brought out the wallet and bought something decent as I know you have a ton of home projects to apply caulking to.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
