Gosh you guys like to slug it out in this section dont you, I've just been reading the Revell Fireball debate? Wow! Regarding this thread I cant realy help MKII but IMHO the model does look a little dark but as I imagine none of us have never seen the real thing who knows? Regarding the 1968 STP Lotus 56, which I have seen, this was dayglo and I believe it was the first time that this paint, developed by Dupont, was used on a racecar.
As a keen photographer over the years I have taken 1000's of race car photo's and yes this paint always comes out as a shade of reddish orange, however this year while snapping in the paddock at the F of S, my latest 'snapshot' digi camera a Kodak Z650, finally picked out the dayglow effect on anything there with a Marlboro livery on it!
