whatever you decide to put on it, i recommend putting a glossy clear coat on it after. me and my chums made a table and the clear coat really water/beer proofed it and for an added bonus, cans slide really well across it.
heres ours:
we also measured and placed dots that the back cups can not go behind (we use the cup away from the edge rule) the middle dot is for 6 cup and the outside two dots are for 10 cup. we also included a friendly reminder to keep elbows behind the edge of the table.
