Terry, considered that but the halves fit together nicely and my prime consideration was all the windows which would have to be masked to paint especially those two round ones. I'd rather do a bit of touch-up on the seams than all that masking. I've also had a situation where I pushed too hard on a clear window that wasn't glued securely and the dram thing pushed in.
I will hold off on the belly and get the top aligned and glued then fiddle with the bottom seam so if I'm off anywhere it will be there and unpainted.
