ordered the top stop filler and filler primer . It begins :-0 . after the finishing it start to get expensive , silicone, fast cast, clear cast. I'm actually just looking forward to working out the lighting. I made a revolving light for a 6-th scale loader years ago but the servo was hidden in the body. I'm not sure I can do them on all the top lights maybe just the middle on. I have to say i'm enjoying this project.
