Done quite a few walnut and birch laminate- and learned a lesson on one last week.
Always looking for a better mousetrap, I discussed the possibility of using a high-build primer over the wood first with NIC, as I wanted to see if I could fill the woodgrain before Cerakoting...
They didn't see an issue with it, so I went with it.
It was a four color, stencil pattern "H" series job (some "wet on wet" because you can only do one partial cure with H series).
Looked beautiful as I opened the oven door- then I sh** my pants as I removed it from the oven.
The entire coating system had "bubbled", or separated from the wood in many areas. There was great bond of the Cerakote to the primer- but the primer itself had separated.
The only theory I have is that, despite the gas-out I did (to make sure all moisture had been driven out) with the metal parts, that the high-build primer had so effectively sealed/encapsulated the wood that as the air within the wood expanded in the oven (it was all low-temp, 160 degrees) it literally separated the coating system from the wood to escape.
Whether that theory's right or wrong...won't be doing that again. Now I have the fun of sanding the remainder off and re-doing the job. Oh well...chalk it up to a learning experience.
