There is a lot of information available on what possible coatings to use for waterproofing a boat skin, but not much info on what amount is needed. Since some people (like myself) have to order this stuff from online, it would be helpful to know how much will be needed depending on what type of coating. Let's assume a 16 ft. canoe with normal beam design & 1050 denier nylon. My guess is that the amount required for that would work for most crafts people want to build.
How much coating should people expect to use if they are building a 16ft canoe with:
1) Zar Polyurethane
2) Famowood Dura-tuff
3) Colean
4) Corey's Skin Boat goop
If anyone would like to throw out relevant numbers regarding Kayaks for others' reference, please do so as well.
