I may or may not be getting a package that includes skid plates, even though I don't need them. Out of curiosity, what sort of maintenance do they require, if any? Does a lot of dirt and stuff get trapped up in there? I should mention I live in the northeast, so while we don't get major amounts of snow, the roads are usually salted throughout the winter (I'm wondering if the skid plates would trap salt deposits up there.)

I'll probably at the very least be getting a front axle skid plate.
