Does anyone know what Yamaha sprays on the inside of their guage cluster to help prevent fogging? I had an experience this winter where it went from 58 and raining to below 0 that nite. In the morning the guages on my 2- Vipers and my RX-1 had fogged over and then turned to a milky colored film on the inside surface. I dis-assembled the housings and cleaned the lens but it felt like there was some kind of film on the inside while I was cleaning them. They now seem to fog over easily even after siliconing the boots. ???
