Looking good LQ.
I usually paint the interior a primer red-brown colour and then cloud spray off white to give the impression of depth. A light wash will help bring out the details too.
Make a little square out of a Scotchbrite scourer pad, and dip it onto a little metallic grey paint so that the paint only sticks to the parts of the scotchbrite that stick out (ie do not dip it completely) so it is not going to drip. Then gently push the scotchbrite onto areas where paint chips will occur - floor, stowage bins, supports, etc) You will be amazed at the result (will e-mail you a pic of what it looks like 'cause I can't link pics here yet).
PS. The reason your kit interior looks different to the pictures
is because of different versions. Acadamy just used the standard M3 interior instead of changing it for the Honey. The British Honey is very diferent to the kit, sorry to say. The round stowage is completely wrong, the Brits didn't use the turret basket, etc. (Had similar probs with the Acadamy Achilles that I am building as it was based on the M10 interior. Still procrastinating about casting main gun rounds because Acadamy only give you 5 spares and a heap of canisters for the round racks, but the British didn't use canisters, they just placed the rounds in modified racks!)
Keep the pics coming. Love your web site too!
