Instruments and electrical seem to be fairly well insulated from the elements. The front bonnet has some good gaskets to keep water from getting into the works. Most of the water that will get into the front compartment will come from the very front where there are openings to the engine area as well as the gaps to the transmission. All the electrical rides above that under cover.
There is no drainage on the floor. Water will come from the rear wheel well through gaps and cracks. There is a slight vacuum effect created from the wind screens. Dirt and debris do not normally come from the top of the cockpit but from under. All the stuff is pulled in from the front or the rear.
The leather appears to be waterproof but the foam cushioning under it won't be. I just wipe it down after a pour and it holds up quite well. Removing the rear upholstery and applying duct tape to all the joins is a good start. It really slows down water and dust.
After a good run on roads that haven't been washed clean by rains I have learned that everything I wear goes into the laundry after. It is unavoidable. I have also stopped wearing white...
