'Warping' on an old acetate promo is really the air escaping from the swiss-cheese plastic that causes the plastic to deform. You may be able to reshape it with warm water. To stop the deforming, you would have to seal the plastic with some type of coating, like clear coat, paint, primer, etc. Acetate is not like polystyrene plastic.

I don't have it yet and it may not be very bad but thanks for the tip.

I once managed to straighten a minor warp on an acetate promo by spraying the body with a lacquer colour coat. It was probably a once in a lifetime event, and will never work again, but it may be worth giving it a try.
