Audrey, sorry, I have no answers other than to seek the advice of the more seasoned HRCCers, including HOGAN, rommer, Robyns Nest, Al Prisco and more. These guys know there stuff!
My boat was wrapped in the clear stuff with no door. I liked that method because, well, frankly, it was too cold to go aboard anyway. Me thinks I should poke a slice in her this weekend and check the status.
Good Luck to all of the HRCCers who do the same and more!!
