Unfortunately sealing has little effect on the warping that happens when wood is exposed to temperature differentials. If the wood panel was extremely dry and you put on a thick coat of epoxy it might be fairly stable, but I'm not sure that is worth the trouble.
You can still use these panels. How much they will warp really depends on a lot of factors.
If you can return them or use them for another project, that might be your best bet.

>>Anyone have tips on sealing/finishing the interior of the walls to prevent this? I want to be sure that run-of-the-mill sealant or stains are not too toxic.
