++1 for the DE. I used to make my own, but the DE's are strong, and curved so they do not bind or bite into your body.
Mud is mud, if it is real mud! Take a look at Frank L's profile pic. You are not going to do anything about that type of mud. But, it is better (imo) to have that mud on the guards than on you shocks, cvds, and pivot points.
For regular "wet" conditions, I have tried spraying them with WD40 and Kal Gard "Prep and Shine" and that seems to help keep a lot of it from sticking (note: if you try the Kal Gard, make sure the body is off the car when you spray it, that stuff and lexan do not get along).
But for really sloppy mud, it is basically pick your poison and where you want the mud to collect.
