Had an interesting shock when I went to glass my hull. I had ordered 30 yards of cloth from System Three along with my epoxy. As I was rolling it out on the boat I noticed something dark starting to appear as the roll got thinner. Eventually I saw that it was masking tape and realized that they must have come up short on the roll and had taped the last 15' onto it to make up the 30 yards. Unfortunately my boat is 17'6" long. I can probably use it under the deck so it isn't a total loss but it made me mad just the same. Just posted this as a warning not to take anything for granted when ordering your supplies, Never in a million years did I think I needed to say "Make that 30 continuous yards of cloth please" ...
