Hello,
I received a private inquiry about the weathering. Since there are no secrets here, this is what I did:
-A mist coat of acrylic brown.
-I did a paper template of the windshield wiper sweep. Put it in place and do another light pass.
-On this particular car, the back was the dirtiest after the race, so I did another pass on the back only.
-A single low pressure (about 15-18 psi) splatter pass, head on, of acrylic dark grey (almost black).
-Finally a black wash with a brush under the fuel fillers, lower front on the doors and air vent.
I did not invent this. I was inspired and encouraged by Jim Drew to try it in my C7R after countless discussions on the topic. Bless the internet!
Thanks,
