I want to keep water out as much as I can but in reality this chassis was not designed for that, and I need to adapt. When I make my own chassis from scratch in the future I will have a seal, but for now we will settle for waterproofing. I will use Plastidip original formula product so I can paint it on with a brush and applied indoors since it is so cold outside.

the rubber is not conductive but it is great for keeping water off electronics.
