(Body guys) Painting interior metal trim 67-71

Skin oils can and do break down interior thermo-set enamels fairly quickly because they were never designed to withstand chemical contaminants. Skin oils can also break down 2K urethane products but it takes much longer. Regular or periodic cleaning will help the longevity of any paint finish.

The heavy transportation refinish industry uses paint systems such mono-coat 2K products that will endure the skin oils and surface abrasion much better than most aftermarket automotive refinish products including the 2K base/clear systems. Because these paint systems are designed to withstand constant diesel fuel baths, greases, brake fluid, hydraulic oil, battery acid, wiper anti-freeze, caustic truck washes, and other nasty chemicals associated with class 8 and above transport trucks.
