Yeah you should be fine with wood you probably don't even have to seal it, as long as its not continuously wet then it will hold up just fine! If you are interested in PVC ones though shoot me a PM I probably have enough material left to make another set or two!
My fingernail only catches in one of the scratches, its the very top scratch in the first picture, how much does that change things? And thanks for the offer! I may very well take you up on that once this winter is over, I'd love to learn first hand from someone with experience detailing and Adams products!
