U-40 FAQ's about Cork Seal

Q. What does Cork Seal do to the cork? Why should I use it?
A. Cork Seal does exactly as the name implies. It seals the cork. This makes the cork easier to clean, less susceptible to sloughing and abrasive damage. It actually enhances that cork feel. It makes the factory fillers stay in place much better.

Q. The directions say use only one coat. What happens if I use two or more coats?
A. The first coat penetrates and seals the cork. The second coat cannot possibly penetrate, as the first coat has done its job and the cork is sealed. So the second coat merely sits on top of the first coat and there is good reason to believe that it will be subject to peeling in the future. After a year or two of usage, if it appears that another coat would be beneficial –lightly sand the entire cork coated handle, and apply another coat.
