Assume you're doing it for the sound deadening properties?


If so, I'd go with truck bed liner....

I used U-POL Raptor bedliner on the entire underside of my 80 including the wheel wells and engine bay. I POR-15'd the passenger tray because it's steel. The only thing I would do different, is after spraying the U-POL Raptor, I would have laid down a couple of layers of a spray on rubberized coating. The noise transmitted past the bedliner coating was significant. It's tough as heck, but not a noise reducer. I have eastwood thermocoustic on 99% of my interior, including over the wheel wells and I am sure a rubberized coating would be a much better solution to outside noise.

Yes. You should be finding factory applied sound deadener/undercoating on both sides of the floor pans and the rear compartment.
