3M has a ton of various tape and film products. I'm still trying to find the transparent film that is used in the auto industry to apply on the deck under the front and paddle bungees to keep the scratches down. Just another one of those To Do List projects.
Another keel strip idea was researched a bit by a friend of mine, he found a paint on truck bed lining product that seemed like it would work extremely well on composite hulls. I'll ask him what it was. I have some older kayaks in the instructional fleet that could be guinea pigs for it.
