"Bar top" Epoxy should work. http://www.eti-usa.com/ You'll have to block off the holes to keep it from running out all over the place. Wax paper with double sided tape works pretty good. If the material size allows you can cut a "frame" and encapsulate the whole thing. Be sure use some type of release agent on the base. Cut as needed. Sand it down and clear coat to bring it back to being "clear". Plus the wood grain looks great with the epoxy coating. Wear "breather" while sanding. The fine particles will mess you up. Good luck
