Preparing and Painting MDO

What procedure should I follow to prepare MDS for 1 Shot or Chromatic Enamels?
Clean the surface thoroughly, then scuff lightly with an abrasive pad. On unprimed MDO, prime with WP1008 Primer. On pre-primed MDO, after using a tack rag to remove any residual sanding dust, roller on your Lettering or Background Enamel. Apply in two or three light coats, as opposed to one heavy coat. If you get little bubbles in the surface, (usually from using a foam roller) immediately re-roller, but slightly "lift" on the roller frame, taking virtually all the pressure off the roller.
