Paint the underlying base color (we used Army Painter, Oak Brown Paint). In this tutorial we have left the base sides unpainted to show the attractive brown finish from the laser cutting.
When deciding to paint the base sides, it's important to note that the LITKO bases and trays are designed with very exacting tolerances. Painting the sides of the bases may be enough to make the bases a very tight fit on our stock trays. We suggest you order the ROOMY versions of the trays if you plan to paint and finish the base sides.
