When it comes to car maintenance, car owners often think of the paint and engine first, while the wheels are the most easily overlooked. But you must know that the visual impression of wheel appearance is the first. It is this seemingly inconspicuous place that can appropriately reveal the taste of the car owner, so don't ignore wheel when equipping your car.
When there are stains on the wheel surface that are difficult to remove, you should use a professional cleaning agent. This cleaning agent can often remove stains gently and effectively and reduce damage to the aluminum alloy surface. In addition, the wheel itself has a metal protective film, so pay special attention not to use paint brightener or other abrasive materials when cleaning. You should also be careful during driving to avoid "hard injuries" caused by scratches on the wheels. Once there are scratches or deformations, they should be repaired and repainted as soon as possible.
So how to repair the wheel with a diamond cutting wheel repair machine(?
First, clean and deal with the dirt on the scratches. Use a razor blade to scrape the shallow areas and scrape the deep areas with a hammer. In short, the silver metal should leak out:
Then use about 600 grit water sandpaper to polish it clean.
To fill the surface with putty, use the special putty for wheel in the set. The resin material of the ab component is indeed very hard. You can add a little less red curing agent (the formula is 20:1).
It is required to scrape as many points as possible to leave the amount of shrinkage and polishing. After drying, polish with sandpaper dipped in water. Use No. 800 first, then No. 2000.
Apply putty for the second time to repair the original defects. This is key and affects the flatness of the final spray paint. If you want to make it easier, you can directly use the alloy wheel repair machine, which can quickly remove surface scratches and treat the wheel surface. Once it's smooth and flat, it's ready for painting.
First of all, you need to do a good job of protection, remove the protective rubber sleeve of the tire bolt, cover the brake disc, and the vehicle logo in the center of the wheel number.
Before painting, use a microfiber towel dipped in absolute alcohol (available in chemical stores) to wipe the painted area over to remove oil and glue.
Spray evenly with a distance of about 15 cm. Do not spray too thickly to avoid sagging. The principle is to spray evenly and thinly, and spray several times. There is an interval of 5-10 minutes, and the surface is dry before the second application. Spray 3-5 thin coats of medium shimmer silver. Finally, spray two coats of polish.
Daily maintenance cannot be ignored. Daily maintenance is also essential. When the wheel load temperature is high, it should be allowed to cool naturally before cleaning. Never use cold water to clean; otherwise, the aluminum alloy wheel will be damaged. It may even deform the brake disc and affect the braking effect. In addition, using detergent to clean the aluminum rim at high temperatures will cause a chemical reaction on the surface of the rim, causing it to lose its luster and affect its appearance.
When the wheel is stained with tar that is difficult to remove, if ordinary detergents do not help, you can use a brush to try to remove it, but do not use an extremely hard brush, especially an iron brush, to avoid damaging the surface of the wheel. In addition, when the area where the vehicle is located is close to the seaside, the wheels should be cleaned frequently to avoid salt corrosion on the aluminum surface.
Small wheel loads are related to our life safety. Paying attention to wheel maintenance and mastering the methods of repairing car wheels are compulsory courses for car owners.
