Has anyone ever applied any type of undercoating on the OSB of their eggs? There are so many new types of undercoating/spray on (or roll on) out these days.....I wonder if it would be a good idea....any issues or problems with doing this? I am certain that this is not the first time this has come up, but I haven't seen any discussion on it. It seems like a good idea to me, but I would surely appreciate comment and suggestions from al of you folks who have so much experience with eggs. Thanks

When I rebuilt my Compact Jr, I used a spray-on black undercoating on the bottom of the new 3/4" Plywood floor I installed. I forget where I got it or what it was. I was "flying solo" back then and did this without the advise of anyone. I used the trailer for about 3 years before I moved up to the Fiber Stream. I did not realize that Oriented Strand Board was being used for flooring. Anyway, after 3 years of use, the floor seemed to be intact (not rotted) but the bottom surface seemed worn, with bare wood showing in spots. (Wind?)

I haven't bothered because it adds weight and won't help much. The vast majority of floor damage comes from ABOVE (leaking windows, roof vents and appliances) rather than from below.

Frederick, OSB is essentially plywood in smaller pieces and the stuf used in most trailers has waterproof glue, like some kinds of plywood but is NOT particle board. All wood rots under the right conditions, even the treated stuf, marine plywood, etc.
