Undercoating 5th wheel?

Anyone ever have their 5th wheel undercoated (Ziebart). I have a new unit coming and don't the frame rusting like my present one is. I stay on the coast a couple months a year. Is Ziebart the place to go? Thanks.

  • Based upon the number of times I have had to rip into the bottom of my 5er to effect repairs, I'd say don't make it any harder to access.

  • If it were me i would get one of the spray in bed liner kits and use that on the exposed metal parts that dont move
