dealing with unwanted chemical offgassing.

[Cruciform]

I recently tore apart and sanded down an old entertainment center to make a display case that will go in our living room.

Since I didn't have the right backing for it yet, the wood has been sitting partially assembled in the garage.

Last night I discovered that my stepson has been using a part of it as his bench for spraying WD40 on things.

I've written the case off as lost cause, because I don't want to poison my reptiles, but for curiousity's sake, will epoxy or polyurethane block the gases coming off the wd40 stains, or any natural toxins (phenols) in wood?
