Wheel well liners or undercoat

[Belvedere]

Figure I need to do something to protect the exposed paint above the rear wheels. Like everyone else I've been considering liners, but liners can be hard to clean behind and cause mud to build up, and cause problems. Is that a big concern with these trucks? I was considering Mopar liners.

My other thought was just pull down the plastic that's already there (why couldn't they just add another small piece over the top?) And spray a couple coats of rubberized undercoat on the exposed surface.

Looked around here, but didn't see much, but oil film and such...

I would do the liners and an oil spray . Personally I’d stay away from any rubberized coating .

I'll consider an oil spray, but I think I'll pick up a set of the Mopar liners.

I would probably do an Woolwax or fluid film and then put the liners over. Rubberized undercoating can hold moisture if and when it starts to lift.
