I'd trust what Covertness said, and I don’t know the effect the lamination would have, but a few years ago I had a
project where I took a rusty old .300 Savage, removed the rust, got the barrel chopped and threaded, used matte
black Aluma-Hyde II on the metal parts, and refinished the stock in a matte black.
For the stock, I used spray-on oven cleaner (maybe called Easy Off) to strip it.
After it was stripped and dried, I used Minwax Ebony stain. I think I put two coats on it. I’m sure if I’d have used
more, it would have been even darker. To seal it, I used matte Minwax Helmsman urethane spray. It turned out
pretty well. Again, it could have been darker, but the Helmsman does end up giving it a relatively flat appearance.
I’m not the best photographer, and these photos were taken with an older iPhone, but in the last picture you can
see how much shinier my black dining room table is compared to the finish of the stock.
It was a pretty easy and fun project. And shooting subs, that rifle is very accurate and extremely quiet
