Plywood for an outside mobile bench

[Specialized29er]

I have a 1800 x 1200 mobile woodworking table that spends a lot of time outside and it get the occasional shower and I'm looking at which plywood to use for a new top and a shelf.

I've been on the Bunnings site to look at plywoods and marine ply looks good but pricey and if possible I'd like to keep the cost to under $100 per sheet.

I bought the table from an older guy that use to cut glass and I welded up some castor wheel adaptors and welded them to the legs.

What do you guys use for outside us, maybe 17mm F14 or F11.

Formply will last almost forever outside, particularly where there is airflow

Form ply. Put a little tarp on it or even a bit of builder’s plastic to keep the uv and water off. Will last indefinitely. You don’t need to spend an exorbitant amount on marine ply, any structural ply with an A bond imprint will last just as long as marine plywood. Marine plywood just has higher grade veneers throughout so voids are minimal
