[Tigers] painting behind the grill

[Owain Lloyd]

someone recently said that the area behind the grill should be painted black
everywhere behind the lower trim strip.
most tigers i see have it either all body color or body color on all the
upper valance and side curves but black on the two vertical panels either
side of the radiator.
can anyone confirm if it is indeed correct to paint the rear half of the
upper valance and the side concave curves in black?

many thanks,
