It could well be a primer,but the reason I say not it it's over everything,bumpers,grill,light mountings etc but the olive green is properly sprayed on the body panels only. The pink was obviously applied when the unit markings were mounted on the bumper as there is a clear outline of the two square panels.
The only exception to the above is the bonnet which was DBG followed by black applied by brush which has then had olive green sprayed over it,no sign of pink anywhere on the bonnet.
Ps I have NO intention of driving a pink LR,even if it turns out it was that colour in service!
