What was the fix for the Flash to Pass button causing the brights to come on in the rain on the '08s? Was it covering the solder with silicone or was it to seal the contacts somehow?

Undo the left switch housing and expose the primitive switch.  Slather dielectric grease over the blobs.  Button it back up again.
