So i managed to make my cruiser hold up to heavy rain and 40mph winds for about 30 miles non stop. I thought I would make a place to share waterproofing techniques.
So I took off my top plate and used window silicone sealer to make a dry cured gasket for the top plate. Then I used plumber's silicone to make a seal for the tail lights and front plate. I packed the wires and internals in with desiccant and wrapped them in plastic before backing them into sealed freezer bags. I would move the shrink wrapped pcb to the top of the system...there are a few methods of sealing it...you can paint it in nail hardener.. or you can paint it in silicone. I chose silicone. I would wrap each screw in plumbers tape to seal and prevent vibration backing them out.
holes in tail lights and peripherals were plugged with combo gorrilla tape and silicone sealer. So far, it has handled about 100 miles in heavy duty rain. If voro invested about 25 bucks this thing would be virtually water proof.
