Among the many things that tend to attack the integrity of your vehicle, rust is the most common and most disturbing. In fact, rust protection stands as one of the biggest priorities for any car owner. A notorious result of oxidation, rust will fast chop out the car, bit by bit, leaving you with a decayed steam- if not checked in time. According to auto experts, you should be careful about getting cavity wax and undercoating rust-protection for your car.
Cavity rust proof wax is meant for the cavities or enclosed areas of the vehicle body. These include all hidden crevices as well as nooks & crannies in the vehicle. Albeit your car has been dipped in times of factory-painting yet paint alone cannot ensure complete rust protection for cavities- in comparison to the car’s exterior panels. Thus, you will have to go for cavity wax sprays that come with deep penetration powers and hence are specifically designed for the enclosed regions. The wax spray will displace the moisture growth inside the cavities, leaving a moisture (& rust) prevention oily wax film behind. You should apply the cavity wax under direct sunlight for better penetration.
On the other hand, the undercoating process is meant for the exposed areas of the car that come in close contact with the road- such as underbelly of the car and wheel wells. Undercoating sprays will also leave waxy anti-corrosive layer on your car body. Besides, the process promises good sound deafening & cosmetic function.
