I know that you can paint with oil paints on plywood...but what about acrylics???? Would you just gesso it first, and then be good to go??

Yes to apply some gesso.

Depending on how 'thick' you apply your paint and on how much, if any, wood grain / texture you want to telegraph or show through the paint would determine how many coats of gesso to apply and how much sanding/smoothing will need to be done.

Also, check to see how dirty/dusty the plywood is before painting or gessoing it. Some plywood is amazingly filthy. You may have to remove dust/dirt/grit/grime and sand (lightly or not so lightly) before you get to the prime/gesso and then painting stages/steps.

Also be aware that plywood come in many different grades and many different wood types. Some of those woods and grades and panel constructions would be better or worse as art substrates.

And almost no plywood is archival, if you are concerned about longevity.

And that's yet another reason to prime/seal the plywood before painting it. To prevent or reduce SID (substrate induced discoloration). IIRC, Golden Paints recommends 2 sealer coats of GAC100 to be applied -before- you apply the gesso coats. You can read about it over on Golden's website, or search through here on WC for SID/etc.

I would gesso all surfaces....., back, sides, front. 2 coats on everything, 3 preferably on the front.
