I'm relocating my P70 control head from a horrible spot, however I'm struggling to find a replacement gasket. I contacted Raymarine directly, but was told they do not sell the gasket. I found a few gasket supply companies, but they are geared towards bulk orders and charge more for shipping than the gasket material. I could probably just use a silicon sealant, but I'd rather find a gasket material. Has anyone done this, or have any suggestions?
