1. Never attempt to repair a split wheel with body filler. This type of serious damage could require aluminium welding. You should speak to a specialist who will advise you whether your wheel damage is repairable or not.
2. If you are repairing alloy wheel rim or face damage with filler, always use aluminium type filler to ensure the strength and vibration resistance that a wheel repair will require.
3. When masking wheels for painting, deflate the tyre from the rim slightly if the wheel is off the vehicle, this will allow you to effectively mask the rubber tyre right up to the rim and avoid overspray. Using TechniQ 96150 Premium Alloy and tyre masking system to speed up this process
4. We recommend the use of TechniQ 220 High Build Etch Rapid Primer on any bare surface metal wheel repairs and for partially abraded original paint. This will result in providing maximum surface adhesion and act as a base prior to application of the wheel colour.
5. Use a wheel primer relative to the paint colour of the wheels for easier coverage when painting, TechniQ Etch primers are available in four colours, Light grey, Dark Grey, White and Black

Can I use any body filler to repair an alloy wheel?

No. Wheels are subjected to intense vibration and heat in daily use. Standard polyester body filler will eventually crack and fall out of any repairs because they will not withstand this level of heat and vibration. Use TechniQ Aluminium Pro 35250 for this type of repair.

My wheel is split / cracked. Can I fill the crack or split with body filler and assume it will be fine because it is not visible anymore?

No, when an alloy wheel is split or cracked it may be dangerous and needs to be inspected by a specialist in order to ascertain if it can be alloy welded or indeed repaired. Do not attempt to fill a split or cracked alloy wheel.
