We have a 1648 Jon Boat, I used about 3.5 rolls. Sticks great! I lightly sanded & wiped with 99% alcohol before applying. *would have been helpful to have a roller tool in applying - you'll alone grateful for a large metal ruler & fresh razors in your tool! Definitely plan to cut in the black seams if you want a seamless look. We've been out a dozen times at least & it's held up fantastic. Feels great under-foot. Rinses off easily after outings & I even shop-vac sometimes if we've gotten a lot of sand in the boat or dog hair (yeah, I love my durable Jon boat but I like it clean! Our friends chuckle at my bougie-jon-boat, but they also tell me they want it if I ever sell it!!).
