I'm replacing a pair of Drake MLB bindings with a new pair of Burton Mission bindings that i picked up on the sale rack.

The question is whether there's any need to cover up the mounting screws and holes left open. The MLBs had a plastic plate (the accelerator pedal) that covered all that stuff up. So snow and water didn't pack down in there.

The burton missions seem to have nothing to cover this up...

Anyone here have any experience with these bindings? Will it pack water onto the top of my board and damage my topsheet or rust the screws? Does it even matter? Seems like you'd want to keep the water and salt off the mounting screws...

Any advice appreciated.
