Protecting expensive avionics from rain in an RV4.
The RV4 avionics are covered by a short fuselage top skin that runs from the
back of the to cowl to the instrument panel. There are nut plated screws fastening this the fuselage forward, aft and on the sides. I am using a siicone window glazing product that comes in many colors. (I am using gray) to seal this skin as much as possible. BUT there still are the screw holes and the air pressures at cruise that wants to lift things up.
What are others doing to protect electronics without compromising cooling?
