I recently made a removable acx bench top that also functions as a top for my sliding tool box in truck. Pretty simple just pull it out so im not working on the ground so much. Realized today that this will get wet occasionally in the winter and even though this is definitely not an end all, be all, as it will get kerf marks ect. Im wondering what i could treat it with because the top layer of acx looks pretty dry. Maybe something to make it last a bit longer. Thanks for any help

this is how we treat ACX in the boating world for decks, floors, boxes, etc.

mix up as much as you need for two penetrating coats – front, back and all the edges. 24 hours apart.
then a coat of oil based house primer and a couple of coats of your favorite oil based house paint.
equal coats of everything front and back will prevent warping

and as for the saw cuts, kerf marks and general use scrapes and scratches, recoat the panel every few weeks or so.
try to remember to CUT ON THE BACK SIDE of the panel – not the pretty show side.
once water gets into plywood from cuts and scrapes, the damage is pretty much done and “could possibly”
start to warp and do ugly things. so try to keep all wounds on the underside sealed as much as possible.
when it has served its time – replace it.

just an option to consider with the other contributions.
