he WPC process is unrivaled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part. It's unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment.

Vapor Blasting Service

Vapor Blasting is commonly known as Aqua blasting, Wet blasting, Slurry blasting and Liquid honing. It is the number one choice for applications requiring the highest quality of surface finish. There are numerous reasons why Vapor Blasting is becoming more favorable over dry blasting and this is primarily because of its two key features; firstly, the finish is achieved by flow of water borne abrasive – not by impact, and secondly because it is a dust free process. The process lends itself nicely to any engine or piece that has a presentation finish.

Vapor Blasting is 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.
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. The ricochet of media is reduced due to the cushioning effect created from the water acting as a lubricant between the media and the component surface. As a result, the angle of the media is changed, producing a lapping effect traveling across the surface, resulting in an even satin/ polished finish

Advantages of Vapor Blasting

Dust free process

Cleans by flow of water not by impact

Simultaneously degrease & blast clean

Water acts as a lubricant between media & component

Promotes longer media life

Produces a 'softer' finish

Avoids media impregnation on soft materials
