The only problem with these DUPLI-COLOR® engine paints, primers and sealers is that your plane might very well end up looking better than you do. DUPLI-COLOR® began in 1938 with touch-up paint for automobiles and developed into a company known for perfectly matching their automotive paints with the original OEM colors. They continue with their innovative products for vehicle refinishing and specialty coatings. We offer their general purpose primer sealer, sandable primer and engine paints. The primer sealer provides a smooth surface with exceptional corrosion resistance. It'll give you better bonding of colors to wood, fiberglass and metal surfaces. Their sandable primer is fast drying and can be sanded for a uniform topcoat. It fills in surface imperfections and can be used on painted or unpainted surfaces. DUPLI-COLOR® engine enamel features ceramic resins that provide superior gloss retention and heat dissipation. This formulation protects the surface from excessive heat and potentially damaging fluids, and gives a finish that doesn't crack, flake or peel. It can be used on engine blocks and engine accessories.
