I've been meaning to glue some sort of microfiber or similar fabric to one edge for wiping away water drops.
The problem with a plastic card like that is that it will scratch the lenses of your goggles. If you're using $20 Gordinis, no big deal. But when the lens of your goggles costs $75, you may be a little more hesitant to use something harsh like that. A Skigee works pretty well, and won't scratch your lenses.

I haven't tried anything like that, but I doubt it would make a difference. The way snow guns work, the water freezes on contact, so just having RainX wouldn't do much good. The other issue is that RainX is made for glass surfaces. The lenses of goggles are plastic, and the chemicals in the RainX could very easily destroy the plastic of the lens.
I'm very particular about my goggles, if you haven't noticed. I've had lenses last for well over 5 years before by taking care of them. Always using a goggle bag or goggle cloth to wipe them down, never using solvents on them, and never ever using paper to wipe them.
