protecting wood/plywood from elements

I am building a generator platform and enclosure.

The platform is built from plywood, tires for cushioning and boards (I
asked a few questions about it here and will post pictures soon). It
will be, hopefully, inside the enclosure and protected from elements.

Enclosure will be built from plywood and boards also. I want to
protect it from elements. Would it be wise to use some oily substance
like they use on decks (cedar deck treatment or some such".

Thanks

Not that I'd suggest it, but the shed I build about 15 years ago is sheeted
with OSB and one coat of paint sprayed on it. Still solid today, no
separation, etc.

Isn't "marine grade" plywood specifically made to live outdoors?

Believe it has more to do with the quality of the interior plies than the
glue.

This is just a WAG, you understand, but how about paint,
specifically, exterior house paint?

Yep, the cheap stuff they use on roofs and outside walls for
sheathing. Cheap because it is made of 4 plys, but works
good for its intended use. Unpainted the stuff goes to
pieces but it still takes years in a moderate climate, so
painted it will last a long time. T1-11 is also exterior grade

How much would MDO cost, say a 1/4" or 3/8" 4x8 sheet?

Yes, there is such a thing and that's what I used to build my
shed/chicken coop. It's been 1.5 years and it is holding up. The shed
is protected by "cedar deck stain oil".

I'm no carpenter but aren't there exterior grade plywoods (CDX?). If you're
not going for "style" but functionality, instead...

I would use MDO (medium density overlay) instead of plywood. This can be
purchased at plywood dealers (Home Depot won't have it). It is very
resistant to the elements, it is what billboards are made of. Finish it
with a good outdoor primer and paint.
