Now that the arm rod handle is constructed it's time to make sure it has a comfortable grip. I used to wrap the handle in black gaffers tape until puppeteer Nick Barone introduced me to Tool Dip. Tool Dip is a liquid rubber made to to cover the handles of tools. It is very easy to use, and it gives your rod a nice comfortable grip, and a professional finish.
The name brand that I use is called Plasti Dip and it's made by Performix. It comes in various colors, I use black.
