I think your only issue would be cosmetic. Elastomeric is the key!

. I’m not well versed in epoxy to know if caulk will adhere to the epoxy very well.


Once sealed with epoxy --that wicks into the wood fibers-- there is no need to caulk. The surface has been plasticized.

If you can't resist the caulk gun (and why not use a good polyurethane sealant instead?) run 80 grit sandpaper over the epoxyed surface to give it some tooth. But not too much.
