Quantity of epoxy for barrier coat?

[Yamaha33410]

To those who have personally barrier coated their 23, How much epoxy did the job require? Trying to get all my supplies ready, Thanks!

My 19 required two gallons for the 5 coats I applied.

Just did an Islander 36 with about 5 gallons of Interlux 2000E.

Depending on where your project is, I have a spare gallon as I bought the 3 gallon can.

If I were you, since Tim used two, I'd buy the 3 gallon can and keep going til it's gone.  Extra doesn't hurt, and 3 gallon cans make neat little stools especially for trailer bearing work.
