The older line up of Mtroniks was indeed water proof and sealed (the escs), but the ratings aint that great though- the truck system (9L motor with the truckpro esc) could do 4s lipo but was limited to 80amps I believe; they have new stuff coming out in the near future.

The MM is pretty waterproof if you tape up the usb port, and I've seen plenty of photos of trucks with the esc out in the snow, stuffed full of the white stuff with no ill effects.
