ALLOY WHEEL REFURBISHMENT PROCESS

- We remove the wheels of your vehicle.
- The tyres are then removed.
- The Alloys are placed in the acid strip bath until all the paint is removed.
- We then Sand Blast or Aqua Blast the wheels to remove all the acid and loose paint.
- Damage on the alloy is then removed using numerous techniques.
- The alloys are then placed in our oven and heated up.
We then primer the alloys and bake them again. - The primer is then ‘flattened off’ to ensure a perfect paint finish.
- The alloys are then heated up again and painted in the colour of your choice and baked off again.
- We then lacquer the alloys to ensure a solid finish and bake them one final time.
- The alloys are left to cool before they have the tyres refitted.
- We finally balance the refurbished wheels and fit them back to your vehicle.
- Ready for you to collect.
Whenever you replace or fit tyres, we recommend replacing the valves. As part of the standard price list, rubber valves are included free of charge. Alternative valves such as metal, chromed sleeved, hidden, or small rubber are available at an extra charge. We accept no responsibility for leaks from old valves that have been refitted at the customer’s request.
We can either, match your alloys previous colour or we can repaint/powder coat the alloys to your desired colour. including; black, silver, grey, pink, blue, orange & many more.
No, maybe one day.
Our technicians match the painted finish and lacquer as closely as possible to the other wheels and the customer’s request. It may not always be possible to achieve an exact match and the final result will be subjective. Our recommendation is to refurbish all four wheels at the same time to achieve a set that matches.
