As for the screened cover, at the moment it is cosmetic only. My intent is to find a suitable waterproof filtering medium to insert under the perforated cover, then place holes in the S&S emblem area. The pre-perforated cover is 1/16" thick stainless I bought online for a few dollars and has the edges peened over to give it the 3 dimensional look."

Ahh...clever.

I wonder how waterproof the material needs to be if at present its deemed ok to wedge the entire bottom open!? I'm trying to think of a fabric that blocks water and particles but breathes: a replaceable section of breathing mask material, cotton tent fabric, landscape fabric, dense sponge?
