Durable, high-performance finish for engines and components

VHT SP403 Engine Metallic High Heat Spray Paint in Titanium Silver Blue is engineered for demanding automotive environments. Its unique blend of urethane and ceramic resins delivers a long-lasting look while resisting harsh heat, rust, and chemical exposure common in engines and related parts.
