Tape should be all that is needed on the cut. Coated side only, who will see the other side. I would also tape the base of your saw, to prvent scratching the surface. All tools should be very sharpe and more teeth the better. Use tape on cut out areas. Drill holes (not large, cope saw blade will work with one hole) and use copping saw, hacksaw blade, or something like that. Set blade to thickness plus 1/8"
