TW, Great article on customizing a racquet on the TW mainpage! The article suggests to use hot glue / epoxy resin to fill the butt. I have a caulking gun downstairs that fires the weather stripping goo. Could I use this? I'm concerned this would add a non-negligible weight to my customization. I'm also unsure if it will adhere to the crevice of the handle adequately or not. Any advice would be greatly appreciated!
