I'm just about to start buidling the refit and I'm dreading it as I've never built anything this complex before. I got the lighting kit too. Stage one was check that the lights work, stage 2 is drill the holes - haven't summoned up the courage for stage 2 yet! How many layers of undercoat do people receommend to stop light bleed? I was thinking 2 matt black and 2 matt white on the inside plus 2 matt white and one pearlescent on the outside.
