So I've made an outfeed table for my tablesaw. The top is made from a recycled piece of 3/4" ply. I sanded it good and got a good flat surface. My plan is to have a router insert at one end. Typically, a work table like this would get no finish, or at most a few coats of wipe on poly. Since this is recycled ply which was previously painted (flat black), I am going to finish it, preferably white. I have 3 coats of Kilz on it now which has been sanded between coats to give a good flat even surface. My initial thought is to just slap 2 coats of semi-gloss latex (I have interior on hand) and recoat when necessary. But, it never hurts to ask. What would y'all topcoat it with? It there something that is (both cost effective) and super tough? FWIW, it is in a covered but unheated space.
Thanks in advance.
