Enamel Product.
The engines and
transmissions of many vehicles offer a special aspect where the grease
and the remains of spilt fuel are the protagonists. These enamel based
effects just need to be painted on. Apply with a brush in different lays
of different intensities for the most realistic effects. For a lighter
effect you can dilute them with White spirit.
