Model airplane dope works great to recoat the floats. It very well may be old stock line laying in the shops. I have a close friend that has been a Lawnboy mechanic for 40years. I'm gonna look in to some viton rubber products, I use them on the 7.3idi builds to help with the ulsd fuel. Il ask are supplier for it and let you guys know what they say.
