That is really good. 

Usually, it just looks as if someone has decided to 'weather' their cars. These just look naturally mucky after or during a race. Impressive.

Thanks Gordon!

That’s the hardest part of the weathering job, giving the car a realistic” final lap “ look without making it look dirty. 
Also every race car has a specific look, a 24h race car looks completely different than aa car that raced a 45 minutes race.
