Has anyone tried the duct tape nozzle? When working with carpenter's glue in the workshop, I will use a created duct tape nozzle. The size of the bead is completely in my control. The glue keeps the tape from sticking to itself. Sometimes, a small straw will give the tool a bit more structural strength if the project is large.
If you can't afford the specialty tips, it is worth a try and there is no cleaning at the end! Just remove the tip and toss in the trash.
