Parts & Engine Restoration

Vapor Blasting is the perfect way to clean and prepare many types of engine components, suspension parts, castings, and other pieces when you want to retain the “as cast” look. The Vapor Blasting process cleans the surface like nothing else and creates the correct look and feel you want on your engine or other high-quality restoration. Vapor blasting is a less aggressive form of blasting in comparison to dry blasting, working just as effectively.
