I use Woolwax on my rig, which sees a lot of dirt. It develops a bit more of a "crust" which is a dirt/Woolwax mixture, after which it's not really wet any more. It's pretty difficult to get off (requires a lot of pressure washer work). Since I use Woolwax black, it ends up looking like a OEM undercoating on the framerails.
In terms of getting dirty working on the rig....it's been a non-issue for me. My clothes do get some Woolwax on them, but they'd also get dirt/grease on them if the rig was uncoated, and I wear old wrenching clothes when I wrench on the rig. Woolwax will come right off you hands and clothes with soap and water (after all, it's just a fatty grease and a non-chemical). I'm able to go 3 years between Woolwax applications down here in MO.
