Hi Tim,
I think after the car makes it onto the road, there will be quite a list of things to still be done. Know what you mean about the tank....and not sure whether to paint it or not. It is actually more noticeable from the sides than the rear, and that pic. is taken from quite low down too. The tank is aluminium alloy, and the car is modelled on a detuned racer, so maybe the look of a non-standard alloy tank is OK. Jury's still out
Cheers!
Glen
