I just got off the phone with Fasco. Spoke with a nice lady but could not really understand her nor could she really help me. She gave me an email to send my order request but what I need to know is how much should I get. I was told 3 quarts is $47.00(this is the non teflon) and 1 gallon $107.00. My boat is 15 long and 5 wide. I just want to do the bottom and up the side say 8-10 inches. I have read that many have had plenty left over after multi coats. How much they bought, I have no idea. Any help would be appreciated.
