RE: Snow
That stuff was there too but what's the point of using a balloon if you just have to cut another hole in it? The plasti-dip method works ok if you combine it with an o-ring on the shaft. But it adds size to the servo and it's usually uneven and crappy looking too. But you can get it in colors if you want.
I just prefer the dielectric method. To me it works a lot better and easier too. Do it once and your done - you never have to fool with it or worry about it again.
