It wasn't too tough since it was just another coat of epoxy. I marked a line with pencil and masked off all but the bottom then applied with a roller.

The canoe is a little heavier than I wanted cause I built it extra tough, but being so stiff it was a lot more enjoyable to paddle than those kevlar rentals.
