Questions & Answers

Q:what lubricant should be used on this tool
by|Aug 18, 2019
1 Answer
Answer This Question

A:  I just use liquid soap that is clear or white. It helps keep the moving parts from jamming and doesn't stain the paper on the drywall. If you lubricate with oils they can get on the drywall causing problems during painting.

              does not work
              This tool does not attach the metal corner to the drywall. It barely even dents the metal. I had to nail on the corner metal.
