I actually purchased a white KeelShield last summer, knowing that I wanted to apply it to the keel of my Crownline 19SS. I finally took the time this evening to apply it. It took almost three hours to apply, but I think the final result looks great and will definitely help protect the keel when pulling the boat up on the beach here at the lake. I followed the instructions to the letter, which included actually drawing an outline of the entire shield on the hull of the boat, thoroughly cleaning the area, applying the 3M chemicals, and the slowly and accurately applying the 7’ KeelShield. Since I’m sure that most folks don’t even know what a keel even is, here is a link to the KeelShield.
