I do not, I did the kiwi grip on mine, had to grind the warn off non skid gel coat off( almost 2 days) face mask and gel coat dust lol) was happy with the look of the kiwi grip, easy to work with, my only beef with the stuff is? It’s easy to scratch and chip,hard to wash, and wear off fairly quick on the abused area of the deck, end up buying a litre every year and touching it up. The guy at the marine shop said the Interlux is a better product. And I repeat kiwi grip will not stick to gel coat, not sure about the interlux. In you case I would definitly stay away from kiwi, the flex( assuming is what cause your issue) it will crack and flake off in no time. And if your like me, blood or rust stains will not wash off without killing your back scrubbing it. My take on kiwi, it’s a band aid that need attention More often then I was expecting, I should of spent the time to redo my non skid gel
