have some type of surface that will resist abrasion. The heavy mastic
type coating, like roof cement or roof coating can do that. The problem
comes in if water and air get behind that stuff. Then that type of
coating can cause rust to actually accelerate. Wheel wheels is a tough
problem. That's why a lot of car makers now use plastic to line wheel
wheels.
the best thing to use is a rust preventative coating that is similar to
the stuff that Ziebart uses. They have an inner panel grade that is
pretty runny, and a slightly heavier grade that works well on exterior
underbody stuff. The military uses at least two grades also on their
trucks also.
(including a number of military grade compounds) and but I have had some
difficulty getting a decent supplier to sell me the stuff in smaller
quantities. (Like 5 gallon cans) JC Whitney sells some decent stuff that
I believe is Daubert compounds put into smaller bottles that fit their
applicator tool set.
