Found a little more time to work on the slab, It's developed a large crack in the pith, starting at a knot, but hey that's what makes it so cool, it's a slab. I sanded it down to 120 grit and filled all the checks and cracks with sanding dust and CA as I went, then sanded the entire surface one last time with 120 grit.
I then coated the entire slab with a thin coat of thin CA in small sections with a cheap plastic squeegee, once done I hit the entire surface with accelerator. Came back about 1/2 hour later and sanded the entire surface back down to bare wood with my belt sander @ 150 grit. Shot my first coat of water based polycrylic to seal it up. Once dry will sand the entire surface again this time with 220 and we'll be ready for the bar top finish.
Once I got a good clean clear seal coat on the slab, it's beautiful, way beyond my expectations, American Sycamore is so cool :icon_thum. The florescent lights are reflecting as white in the picture it the polycrylic may not be completely dry and remember my camera is a POS.
Thanks
