Road salts are the biggest reason for rusting of cars. These harmful salts are mixed with sand and strewn across roads to defreeze snow. While the abrasive sand particles cause scratches on the metal surface, the salts aggravates rusting by catalysing the oxidation of the metal. As a result cars start to rust from bottom up. The best solution to avoid this damage on cars is to undercoat
its lower side.
Here are some important things to know before you choose to undertake the process.
solutions come in spray bottles and with a clear set of instructions. It is important to go through the instructions and pay attention to the smallest aspect. Details pertaining to time taken to dry, distance between the bottle nozzle and car surface and safety precautions must be duly acknowledged.
Set the Right Place
When a car has to be undercoated, it must be taken to the nearest automobile dealer. It must be hoisted, washed and dried completely to make it ready for the undercoating. It is recommended to execute the process in an open space as these sprays contain toxic substances with a strong odour.
The Obvious and Not-So-Obvious Parts of the Car
Some areas on the underside may be tricky to be covered completely by the spray. For instance, the area behind the exhaust system, the control arms and fuel lines are some difficult areas to be protected.
Coat More Than Once
After the first coating allow few minutes for it to dry completely. Follow up with another coat to ensure all parts of the underside are covered.
