Its All About the Paint in General Automotive Talk (Trucks and Cars) Posted March 6, 2017 · Edited March 6, 2017 by peteski Glossiness of the model's paint is not the main deciding factor when the model has so many layers of paint that they almost hide the door lines or other details. It might be polished and shiny, but it doesn't look good or realistic.As far as judging goes, when my the judges judge models at our club's model contest, we use the pont system. The model gets certain amount of points for overall paint finish. That includes body, interior, undercarriage and engine compartment. Pretty much all the painted surfaces. If the body has a superb paint job but the interior or engine is poorly painted, that model will get fewer points than a model which has quality paint jobs on all of its components.
