When it comes to your alloy wheels, it can be heartbreaking when they get scratched or damaged

From small scratches to bigger scrapes, damage to your alloy wheels can be as a result of various causes - such as high kerbs or deep potholes. Whatever the cause of the damage, getting your alloy wheels touched up to hide alloy scuffs doesn’t have to be a difficult process. After all, it happens to everyone from time to time, making it tempting to simply leave any small damage untouched.

However, having a set of unmarked, clean alloy wheels often speaks for the quality of the rest of the car - and can ultimately make it easier to sell your car, should you choose to in the future. While going to a garage or an alloy repair service can seem like the best solution, it can be an expensive process. For minimal damage, such as small scratches, tackling the issue on your own with a DIY alloy repair kit can be the most cost-effective and straightforward method.

DIY Alloy Repair Kit

When you purchase an alloy repair kit, they usually include:
  • A filler/primer
  • Paint (brush on or spray)
  • Sandpaper (fine and coarse)
  • Lacquer/clear coat
  • Protective gloves
  • Application tools, such as brushes, wipes and sponges

Getting Started

Before you begin, ensure that the alloy wheel is clean. This can be done by using a soft sponge with washing up liquid to remove all traces of dirt, grease and brake dust, as these residues can get into the paint and affect the overall finish of the wheel. If the damaged area is close to the lip of the wheel, be sure to mask off that part of the wheel so it is protected. Using the coarse sandpaper, sand and file down the cuts, jagged edges or scratches and continue to do this until the damage is completely leveled out. Now using the finer sandpaper, go over the area again to smooth it out. Remove any dust that sanding may produce with a damp cloth.

Filling It In

Ensure that you securely mask off the rest of the wheel and the surrounding car body before applying the primer/filler. During application, spray 3-4 light but even coats over the affected area. If there are any uneven or bumpy areas after the primer/filler has dried, file them down using the fine sandpaper.

Be sure to wipe away any dust that sanding down may leave behind. Before applying the spray or brush-on paint, test to see if the paint matches the silver of your alloy wheels. If so, apply the paint in thin but even layers, ensuring not to leave any application marks such as brush strokes. Allow the paint layers to dry thoroughly; if the layers build up too high or form clumps, simply sand it down with fine sandpaper. Finally, apply the lacquer or clear coat to ensure that the area is protected and allow to dry thoroughly. Once it has dried, you can remove the masking paper - and your alloy wheels should be successfully scratch free!
