VHT Engine Coatings is a unique formula of urethane resins that resist fading, strong solvents, corrosion and temperatures of 550° F. There are no other air dry products that can withstand the temperatures or strong solvents used in today’s gasoline or cleaners as well as VHT engine coatings. These coatings have been formulated in a wide variety of exact match engine colors for complete restorations or customizing engine components. Application: Clean surface thoroughly, removing all grease, oil, loose paint and rust. Sand previously painted surfaces lightly being sure to feather all rough edges. Wipe part to be painted with a tack cloth being careful to remove all dust and paint particles. No primer is required. Do not use in temperatures of less than 70° F or on parts that are less than room temperature. Apply VHT engine coatings directly to the surface to be painted. Apply a smooth even coat and lightly sand for a primer coat or spot prime.
Hold can 12 to 15 inches away from surface and spray in one direction using long even strokes. Repeat the process in the opposite direction. Wait approximately 30 minutes before recoating. Excessive coating build-up is not necessary or recommended and will cause blistering and loss of adhesion. Apply only enough coating to color surface evenly. If touch-up or recoating is necessary after 4 hours, a light sanding may be needed.
Curing: VHT Engine Coatings will air dry in one hour and cure overnight. Baking for 15 minutes at 300° F and then 30 minutes at 350° F improves finish and provides a more durable surface for handling, resistance to salt-spray, chemicals and humidity. Curing may be accomplished by the inherent heat of operation, such as encountered in engines and exhaust systems or by baking in an oven, infra-red, blow torch, etc. VHT Engine Coatings can also be cured by starting the engine and running at idle for 15 minutes and letting cool. Restart engine and run for no more than one hour and again let cool. If the engine is operating normally, this will bake on the finish. All curing must be done slowly.
