Hello, i have 2015 airstream and i already have corosion on the belly pan. I took the trailer in november and store it for the winter and didn't wash the belly pan. So calcium did a litle corosion. I put some oil all over it, but I am tiking to paint it or put some Bedliner. Isit a good idea?
It would be a miserable dirty job spraying bed liner on a belly pan, but if you did it right by sanding it well and used an epoxy (two part) bed liner it would last a very long time.
The bellypan is like the underside of a car. It's not meant to be pretty, but to protect the frame and floorboards from excessive moisture and debris. Lots of SOB trailers don't have any pan, just some sort of clothlike covering.
If you're so inclined, you can try and clean it up and paint it with some type of paint or undercoating. Just make sure you don't try and seal it up totally on the bottom, you want any moisture that gets behind it to be able to leak back out quickly. If it were me, I'd concentrate on keeping the shiny side shiny and looking for any abnormal leakage on the bottom.
Get some stuff called Aluthane. It is an aluminum filled water cured urethane (silver) similar to POR15. I would hose off the belly pan to get dirt off and put this stuff on. It likes rough corroded surfaces. I would think the weight of bed liner would not be a good thing.
I keep mine coated with CorrisonX along with the stabilizers......in fact everything underneath the AS. I picked this tip up from reading/learning about Filliform corrosion prevention. It does leave a waxy residue but no rust or corrosion so far.
