Essentially sanded the slab of wood slice until level and soft and the way I wanted it to look. Placed into laser deck and made sure the are was level that was being engraved. 

Engraved the work onto the area, sanded some more, added some gloss finish via spray paint allowing each coat to dry completely in between, spraying each coat flat to prevent drips. 

If using the Wood slice, as in the photos,  one should also gloss over the wood sides and the back side if the wood slice is going to be spending time out of doors, to seal the wood.
