I have a slab of  Juniper from Central Oregon that is about 35 years old. I am wanting to make it into a bench to put inside the front door of my home. It’s been cut and plained and is ready to work with. It’s a beautiful peice of wook. My question, How do I finish it to give it a laquer type finish? Similiar to what I’ve seen guys to who make fireplace mantels.  I want to perserve the beauty of the wood but also make it a functional peice of furniture.  Thanks.
