Greetings. I was crawling around under my Pup just inspecting it and realized that the wood is uncoated. It looks like just straight MDF board and I'm wondering about the rains of the PacNW that we experience out here. Chatting with some friends they recommended using Flex Seal and coating the undercarriage with that stuff, but I'm wondering if there is a different solution. Any ideas or suggestions? Cheers.
