Aluminium panels are popular in modern cars because they’re lightweight, durable, and rust-resistant. But repairing aluminium is not the same as repairing steel. It requires special tools, controlled heat, and experienced technicians to repair it properly. That’s why choosing a specialist car body shop in London is essential if you want a safe, high-quality, and lasting repair.
Let’s look at how the repair process works.

Damage Assessment
The technician will start by assessing the damage. A panel that has deep creases, sharp folds, or extensive stretching is more likely to be replaced, while minor scratches and dents can be fixed without panel replacement.
The panel may also need replacement if it has already been repaired several times using heat. This is because the heat weakens aluminium, and with several repairs, the metal reaches a point where further repairs are not possible.

Why Aluminium Panel Repairs Are More Complex Than Steel Repairs?
Dedicated Equipment
Aluminium can chemically react with steel and result in galvanic corrosion, which can penetrate the paintwork and damage the car body. To prevent this, your car repair shop in London will use dedicated hammers and grinders that haven’t been used on steel.
Careful Heat Application
Aluminium lacks metal memory, so it does not spring back into its original condition after applying pressure. It’s reshaped carefully using heat.
Careful application of heat is important because overheating can damage aluminium permanently.
Best Practices to Repair Damaged Aluminium Panels
Use the Right Tools
You need dedicated tools to work with aluminium. Mixing tools that are used on steel can cause corrosion. Always keep your aluminium repair tools clean and avoid using them on steel or other metals.
Choose Bonding or Welding
Some aluminium panels require welding, while some require bonding or riveting. Follow the manufacturer’s instructions to choose the correct method.
Avoid Over-Sanding
Aluminium panels are not as strong as steel and can lose strength if they are sanded too much. Only use gentle sanding or grinding when required to protect the metal.

Apply Heat Carefully
Aluminium is heated in a controlled manner to restore the metal to its original shape. Too much heat can permanently damage the panel.
Check for Hidden Cracks
A damaged aluminium panel may have hidden cracks or stress marks. Checking the panel thoroughly can help restore the panel’s original strength and help it last longer.
The Finishing Process
If the panel requires paint, the technician will first apply a thin layer of etch primer. It contains phosphoric acid that etches into the aluminium surface.
After the etch primer has cured, the technician will apply epoxy primer on it for proper adhesion of filler over primer. Once the surface is ready, the technician will paint the surface and seal it with a clear coat.
