Realistically, how much water can an MMM handle?

[Slowkrawl]

Hey guys, the title is pretty self-explanitory. I am trying to figure out a way to keep the snow off the speedy in my savage flux. So far I have tried afro-engineering some tape around it which worked alright, but there was still some water on it. I want to keep it water-resistant but still be able to breath. Kind of contradicting if you ask me

So back to my original question though, how much water can the speedy take before it goes to smoke land?
