Joe,
Take the boat back and have them apply more coat it to the bottom, Actually demand they do it. I bought a willie in 97. It had caot it on the bottom. It was real thin and was cracking towards the rear of the boat. Water got between the coat it ad the bottom, when t froze half of the crap fell off. I took the boat back to the dealer and had them redo it. It took 2 times before they finally got it right. For the price you pay for that option you should have a 1/4 of the stuff on there. An another thing, If you ordered you boat with clear coated interior make sure there is actually clear coat on the zolatone. Wille makes a great boat but thier paint department blows goats.......
