So are you saying that it mosts up, or that the water leaks down between the lid and the visor? If the latter, then its the seal at the top on the visor (Well thats obvious) and i would make sure that the visor is mounted properly. If it is, pack out the seal with some insulating tape or similar to see if this keeps it at bay. If you have a pinlock, there should be no reason to open you visor. As for the outside, i use a Xerox product which is pretty darn good. I had limited succcess with rainX
