Hello, /o/. I recently rekindled my desire to pick up an Iltis for a Daily Driver. I'm not concerned about parts or anything, what I'd like advice on is what sort of products I could use on the body/underside to protect it from winter abuse, salt, sand, etc.
Most dealerships will give you a coat of wax on the underbody. It's not much but it helps if you drive on salty roads. Costs about $50-100.
