I have several boats. A few with Valleys, one with Sealect and one with Kayak Sport. I like the Valleys best but as everyone knows, they have a shelf life. I've had the Sealects for 2nd season now. They work fine but some times a bit stubborn to get on. And a more stubborn when it gets cold. I believe the Sealects are a plastic compound and not real rubber. That's why Valleys crack because they are a rubber compound. The Kayak Sport ones work fine, are soft and so far so good on those. They're about 5 yrs now. I have replaced Valleys many times and yes, it's expensive because all three seem to start going around the same time. I still like them the best but more longevity would be appreciated.
I too hit them with 303 etc. but I guess UV in the air seems to attack them plus... ever feel the roof of your car on a 100 degree afternoon? That's what they endure regularly.
