I have a small deck (10 by 12) that is going to be up for 2-5 years.
I've priced composite decking, and even 2 by 6, but they are "costly",
and the 2 by 6 is poor quality.

I was wondering about 4 by 8 panels, 5/8 or 3/4 inch (joists are 16" oc)
as a "temporary" surface. Maybe chipboard or outside plywood. What could
I do to it to have it last that long?

I thought about priming and then a rubberized coating, especially on the
edges, leaving the bottom bare. Then thought about treating the bottom
side as well, but couldn't come to a conclusion. Also thought about
raising the plywood off the joists by using angle iron so there was no
wood/wood contact.

What does the collective intellect think?

Grain bin drying or aeration floor? It's galvanized metal with
slots. It isn't smooth so it would have an advantage during snow or
ice storms. You'd probably be the only one on your block with a deck
like it.
