The vinyl may slow rusting down...but yes they can rust out.Thank you everyone for the guidance. We settled on 2' apron which will be a couple of inches below grade. Now my latest worry is rust. I am using galvanized, vinyl coated 0.5" hardware cloth (16 gauge). Spending a lot on that. Won't it just rust away under the dirt? I see lots of people do predator aprons - has anyone lost them to rust?
Just read a post about that.....biggest problem was they didn't have roof overhangs out far enough to keep rain off of it.
