Yes, definitely needed. Fluid Film or comparable product. Once you remove the wheel liners you will see all the areas that trap salt and road debris. Here in the rust belt I don't think the Maverick will last very long without salt protection. Mabett's mud flaps and underbody shield will help too.Any insight on the desirability and/or recommendations for this?
So Fluid film will never "go away" but it can get brushed off of surfaces or you may not have totally coated it to begin with. Generally you'll need to reapply every year for the first 3-4 years and then it will no longer be necessary because you'll have a film of it and dirt now protecting the underside.How long will Fluid Film last before requiring reapplication
