What does everyone do to eliminate rider cabin dust?

I ride in pretty dusty areas and hate all the dust that swarms into the rider cabin area. I have the hinged wind shield like NMK, solid back like NMK (yes, I totally copied his look), and doors. In the process of working and cleaning my ride I noticed about a billion little places where the dust gets in: under the dash, odd 1/4 in holes in the firewall area (maybe for later after market options???), by the hand break, seat belt buckle in, old frame rails for stock netting and grab handle, etc.
AND, I have watched NMK's hot to videos and seen plenty of foam tucked in all kinds of places. Clark, maybe a video of what you have done for dust abatement??
