Mazda 6 How-to: Alloy Wheel Troubleshooting Tips
Alloy wheels are lighter but provide more strength and better heat conduction than the usual wheels. It is also a plus point that alloy wheels look aesthetically better than steel, so while alloy is considerably more expensive, it is the preferred choice for seasoned car enthusiasts. While an alloy wheel might seem like the golden sample of wheels known to mankind, it is not without flaws. A poorly-designed alloy wheel has a tendency to elongate over time; and based from experience and common sense, elongated wheels just won't do. It not only diminishes the performance and drivability of a car, it also provides plenty of room for vehicular accidents. Below are other problems associated with alloy wheels, and how you can avoid them:
The lacquer on the rim is insufficient.
Have you ever experienced going to a vulcanizing shop to check your tyres, and the mechanic tells you that there is dust buildup from the inside of the wheel? That dust buildup is rust, and it is a common problem caused by inadequate supply of lacquer. While you can clean the rust buildup, a quick clean-up job won't do as well as a long-term treatment. What you need to do is fairly simple, but you can't do it by yourself. Have the alloy refurbished by shot blasting, powder coating, and lacquered. This process will make your wheels look new, and the lasting effect will endure a good number of years on the road.
The paint is cracking and bubbly under the powder coating.
This is the problem when you lacquer the alloy wheel yourself. It is a common mistake for Saturday Mechanics to spray lacquer over enamel in hopes that this will strengthen the coating. Believe us, it won't. If anything, it will just prevent the automotive paint from adhering to the component perfectly. The proper order for this project is to sand the alloy wheel, coat it with the specified powder for the part, coat it with lacquer, and paint it completely. If you feel like you are not qualified to this on your own, it is always good advice to trust that instinct of yours, and forward the job to a professional.
