I did seal up ours quite a bit a few years ago, and more recently added a mudflap at the rear of wheel well, for other reasons.
To seal it, I used silicone to caulk up holes and seams toward the wheel, and made a rubber flap to go over the upper holes on the inboard side of the box. Those are the holes that let in almost all the dirt and water. It doesn't seal tight, as the cables are there, so you get air circulation, but any dirt and water go down and out the bottom holes and don't get to the slides. I removed the slides and cleaned them completely, and bolted them back in, in case I need to do it again, which I haven't in over 3 years. I put a very heavy layer of grease on the slides, covering the entire metal surface. The grease will grab any dirt that gets there and keep it and any water out of the moving parts of the slide. When the grease gets a bit dirty, I just wipe it off the surface, with the dirt, and put on clean grease. I have not had to regrease the moving parts to this point and it still slides very well. The compartment mess has been reduced by at least 80-90%.
