IMHO, the Clooney, Batman and Robin is the worst Batmobile. An open cockpit? Yeesh.
Anyway, I build this one and had the same issues. I did it in semi-gloss black and for the chromy bits, I used a heavy black wash. The result I rather liked and it gave it an industrial look that I liked. I also kept the center wing as one piece. I won't hijack your thread by posting pics, but if you want to see them, I can PM you.
Nice work. I like the blue tinted parts.
