I wonder if you could combine techniques and squirt the product from the Six-10 cartridge into a syringe, then use that to fill the hole from bottom to top?
I have my exterior cabin top rails removed for refinishing and I would like to pot the holes before I reinstall them. I also have interior hand rails that are also attached through the cabin top so I want to pot them at the same time.
