The Refurbishment Process

Alloy wheel refurbishment is best done by a professional. When the professional refurbishes your alloy wheels, the tyres will be taken off the wheels. Stripping the wheel of the existing finish must be done prior to any work. This allows for the ultimate adhesion of the new finish. This also allows all the damages to be assessed for repair. A chemical approved for stripping alloy wheels is used so there is no worry about damage to the wheels.


  • After the stripping process, blasting the wheel is done to remove anything that might remain of the finish.
  • This is also helpful to remove corrosion if there is any present within the wheel.
  • This is also beneficial for preparing the wheel for alloy wheel refurbishment.
    • The damages on the wheels, such as scuffs and gouges, will be inspected and noted for repair. If there is only a light scuff on the wheels, rubbing them down should be sufficient. Deeper gashes in the wheels will need to be filled and sanded. This is a process that is quite similar to body work performed on vehicles.

      Powder Coating

      In most cases we would recommend a full refurbishment of your wheels to achieve a 'good as new' look. They will go through a 3 stage powder coating / paint process to give a very durable and high gloss finish.

      • Tyres are removed as are any weights and valves.
      • Wheels are then hot pressure washed to remove excess dirt & grime.
      • Placed into a chemical stripping tank to remove old paint & lacquer coatings.
      • Hot pressure wash rinsed.
      • Wheels are lightly grit blasted to remove blemishes and corrosion.
      • The wheels are then inspected for damage especially the lips of the rims any cracks & deep scratches on the rim edges, faces and spokes will be filled in by alloy tig welding, they will then be machined using various techniques & hand tools. They are then always finished by hand.

      Next the 3 stage powder coating / painting takes place.

      The wheels are pre-heated in an industrial oven to 200 degrees for 20 minutes to de-gas the alloy then a powder coat primer is applied.

      Next the wheels are cooled to 60-80 degrees and if they are having a colour coded or bespoke finish they are spray painted and put back into the oven for a further 40 minutes to cure.

      The final powder coat clear lacquer is then applied and the wheels are then put back into the oven at 200 degrees for a further 20 minutes.

      Once cooled the wheels are fitted with new valves and the tyres refitted and are electronically balanced. Stick on weights are placed on the inside of the wheels so that it does not spoil the appearance of the finish.

      Diamond Cutting

      Although powder coating is Cobra Customs most popular and durable alloy wheel refurbishment service, diamond cut finishes are also a very desired finish. Many cars are fitted with diamond cut finished wheels.

      Cobra customs can reproduce this finish. Diamond cutting is a very precise process and takes longer to reproduce than a powder coat refurbishment. The refurbishment of a diamond cut wheel is impossible to do as a touch up/ mobile as it requires the use of lathe.

      Corrosion in diamond cut wheels is very common, applying lacquer to a polished surface simply defies gravity it is very difficult to achieve a long lasting finish when applying lacquer to a shiny surface, small stone chips allow water in behind the lacquer and in time causes the lacquer to deteriorate and appear cloudy.

      Diamond cutting involves removing a thin layer of alloy from the wheel using specialist lathing equipment. Diamond cut wheels can only be refurbished a number of times as too much alloy would eventually be removed. You may wish to consider our powder coat refurbishment as a durable and long lasting refurbishment method instead.

      With our bespoke in house diamond cutting lathe we will provide you with the highest quality finish and the quickest turnaround time.
