To most car mechanics and salesmen, rustproofing is something that they use to con car owners promising protection for their cars for a long time. This may be true for car owners who live in areas where it frequently snows but for some owners who are not located in places where it rarely snows, rustproofing would only mean additional unnecessary expense.
Rustproofing or otherwise known as undercoating protects the top layer of your vehicle but its protective function stops there. It comes short in protecting the entirety of its car. But this does not mean that one has to forgo the process of undercoating altogether because it has its advantages.
In the olden times the process of rustproofing or undercoating involved the use of asphalt tar and pine resin. These components were applied to the iron components that are most exposed to salt-air exposure.
There are a lot of types of undercoating. It comes essentially in a form of a thick glue that is wet and sticky and can remain in this state the longest time possible. Undercoating contains binding agents such as epoxy and asphalt and solid elements such as ceramic nodules or fiberglass. Fiberglass helps strengthen the undercoating. There is another type of undercoating and this is the rubberized undercoating that is sold in stores. It is a sealant that needs to be sprayed on your car. Although it does provide protection, such protection cannot be sufficient because of the thin layer it gives to your car. Also, this type of undercoating is prone to development of bubbles.
The downside of undercoating is that if it is left over a long period of time, the undercoating will harden and will chip away. Undercoating entails a lot of procedures. It also add a significant amount of weight when it is applied in excess. It can also increase the rate of the vehicle's decomposition. When the undercoating is not evenly distributed or sprayed on, the thin portion that is beside the thick portion will chip away which will lead moisture to be trapped in between the thick surface and the car's body which will again significantly increase the corrosion of your car.
According to car experts, factory undercoating is a process that will only steal a lot of money from you. If you still want to have your car undercoated by mechanics make sure that you observe proper diligence in the application of said procedure.
