I made some out of a sheet of PVC material that is used on dirt track race cars. Made patterns cut the pieces out with a band saw, finished the edges on a belt sander and used dzus fasteners for install so I could remove for access to the clutch can. The slick finish lets the dirt and mud slide off and makes it a lot easier to clean. As far as heat, I installed a 12" cooling fan and a louvered panel where the plastic dog house cover is. Going to make some insulated panels for under the seat this week
