I built a "Beetle Bomb" several years ago. Sometimes it's nice to see a Bearcat in different colors other than Navy Blue. I'm sure that whatever color scheme you decide to use will look fantastic !
Just like you said, yellow is very translucent and hard to get good coverage. The white base is a must for a decent looking yellow. (But light gray will work just as good). The key is having a uniform light colored base coat for the yellow. White just makes it pop a little more...
Jeff, Allan is correct with the reveal date. Since the GB was going for such a long time, we decided to let the builder decide if they wanted to post their project when it was completed or wait until mid February. The choice was theirs.
Allan, I'm 99 % sure that the "Beetle Bomb" was never flown with red markings. In every photograph I have ever found of the real plane, the letters were always blue.
Here's a few for you guys...
In some of the pictures the leading edges of the wings AND tail appear to be polished aluminum. In other pictures, it looks like just the leading edge of the wings were polished. Yet here in the third and 5th pictures I posted the entire plane looks yellow, with nothing polished at all. It was probably due to these pictures being taken at various times of the plane's career. It was something that probably evolved over time.
It's amazing how dirty the Pratt and Whitney R2800 made the plane look in a very short time. Between the exhaust stains and the oil 🙂 I'll bet this kept the ground crews very busy with clean up...
Hope these help...
