8000ft

I can't remember the brand name off hand but you can get it at Ace Hardware. It's used for dipping tool handles in to provide better grip. I think...........ok I just went into my shop to check, I have two, Plasti-dip and Grip&Guard. They come in black, blue,yellow,and red. Juats dip your servos into it about a 1/2 inch up the wires, let it dry over night and trim around the spline shaft and your servos are 100% water proofed.

hope this helps, I run in snow alot so i've gotten pretty good at water proofing.
