Why Us?

We understand that fellow enthusiasts really want to restore their own motorcycle or car, but would like somebody to take on the tasks that can be time consuming, difficult or impossible without the right equipment.  We can take individual components and make them look new again using a range of techniques and equipment from shot blasting, vapour blasting, ultrasonic cleaning or zinc and nickel plating. All these techniques are difficult to do yourself at home, so we've invested in the equipment and expertise to take the difficulty out of it for you.

In addition we specialise in the service and restoration of carburettors of all makes and sizes and all levels of service. Our carb page has a more detailed description of what we offer.

Pretty much anything can be restored, depending on the time and effort required to be put into it. We understand the financial implication of that statement, so we will discuss with you what you're trying to achieve. Is it a daily drive/ride or a concours show vehicle. Understanding this enables us to give you a number of different options for a range of results.

Until April 2019 we are offering an extremely competitive rate of £35 plus VAT per hour. Ultrasonic cleaning is included as part of a carburettor service and restoration.

We are based in the Bristol Road area of Gloucester near the quays, but can help wherever you are.
