Hi Chris,
I got some more info regarding the SBD. I Can't find any examples of an overall Glossly Sea Blue. the Dauntless was phased out of front line service from mid 1944. The only thing close that I've seen is a SBD-4 target tow in Sea blue and insignia white.
If you want something different you could built the army designated A-24 Banshee. There's a couple of different schemes including a all natural metal finish or olive drab over light gray.
If anyone wants to build an SBD you've got to get the Squadron Walk around No. 33, it has fantastic pictures including plenty in colour.
hope this helps,
JasonC
