What should we do with a crack in the body
The crack in the body requires the choice of the appropriate treatment based on the type, size, location and severity of the crack. Painting is required if a slight crack in the paint can be treated deeper by polishing. Small cracks in the body metal are welded, rustproof and spray paints lead to large cracks that may replace metal plates. Small cracks in windshields that can be repaired with resin are replaced. In any case, there are different situations in which specialized maintenance staff may be consulted if necessary。
A polishing exercise at the 4s store when there is a slight crack in the paint is a good option for repairing the crack to some extent and restoring the paint to light. If the crack is deeper, the persistence of the unpaved paint will need to be addressed and the quality of the repainting and the construction process closely linked。
The treatment is different when the body metal cracks. Smaller cracks can be repaired by welding before a series of operations, such as grinding, rustproofing and spray paint, can restore the car to its original condition. If, however, a larger crack affects the body structure, the metal plate may need to be replaced. The sustainability of weld restoration depends to a large extent on the quality of welding and the availability of rustproofing。
The treatment of cracks in windshields varies. It is also relatively easy to repair smaller cracks using resin. However, if the cracks are large or the situation is serious, the windshield can only be replaced. Persistence of resin restoration is influenced by multiple factors, such as the driving environment, and the cost of replacing windshields is relatively high。
In addition, the plating brush is an option for dealing with small cracks in the body, which are simple to operate and cheap to cover the cracks quickly to prevent rusty but colour matching may be less precise to repair relatively roughly only for less visible cracks. Also, the ease of body repair works has had some effect on small and medium-sized cracks, with the potential for ageing in the long run。
In any case, when the body cracks occur, the owner needs a calm analysis to evaluate the trade-off between the advantages and the disadvantages of choosing the most appropriate approach. If they do not, they must seek the help of a professional maintenance staff to ensure that the cracks are properly handled so that the vehicle is in good condition to ensure the safety of the vehicle。
It's normal to have a crack in a tire
Tyre cracks are common in some cases and normal in others require attention and timely replacement。
Normal cracks include small cracks on the treads of tyres, which are a natural aging of tyres. This occurs when tyres are typically used for about three years, provided that the cracks are small enough to drive in urban areas but not at high speed。
The smaller cracks on the surface of the local rubber surface caused by the rolling of the treads on the ground by overwhelming objects such as stones are also normal as long as they do not hurt the fetus, but only reduce the useful life of tyres to replacement。
The following cracks are deep in the face of an abnormal tyre that needs to be replaced, at a time when the tyre is already seriously ageing and has lost its ability to use rubber. Fragments on the side of the tyre need to be immediately checked in the shop for replacement, as the side of the tyre continues to operate in vulnerable parts of the tyre. 1. 6 mm must be replaced if the fracture is too long and too deep to reach the standard depth of the tyre graft or the ability of the tyre to drain is reduced. Tyres are used for a short period of time, but there are many cracks indicating that ageing is severely in need of replacement. The presence of drum packs must also be replaced in a timely manner, otherwise they may affect vehicle brake performance。
Regular cleaning of tyres to slow the ageing rate of tyres by day-to-day parking, as far as possible, in the shade to prevent sun-burning vehicles from stopping on clean and clean floors to avoid the appropriate use of beauty products, such as tyre tungsten or tyre wax, for the purpose of slowing the ageing of tyres。
In any case, more attention should be paid to the condition of tyres to ensure the safety of motor vehicles。
