Automobile restoration includes several aspects in which an old car can be revived. The main purpose is to disassemble its parts, do a complete cleaning and repairing, and if need be, replacement, and then putting them all back together as it was. This is the internal story of car restoration. But a vehicle is not only about its inside machinery. How it looks on the outside is also a huge factor, especially if the owner wants it to not only feel brand new but also look the same.
This is where wet sanding comes in. It is a process of treating the paint of the car so that its finish looks like straight out of the factory. In this article, the exact need and function of wet sanding, and its procedure is further elucidated.
What is wet sanding?
Wet sanding is giving the paint of a car a completely new, polished look during its renovation. It is a popular practice done during auto restoration in Russia. Here, with the use of a wet sandpaper, the paint of the car is polished to give it the shine of a flashing new car.
Why do you need wet sanding?
Your car or truck suffers equal damage on the outside and the inside, especially in rough terrains. More than scratches and dents, the main problem is the dullness of the pain. Over the years, the shine wears off and the car looks old.
But even if it does not, it would not do harm to do wet sanding on it.
If you look closely at the body of a brand new car’s paint against the light, you can see very minute undulations on the surface. That is a very normal thing, as the paint by itself cannot plain itself out while drying. But this affects the light reflection, and thus the shine factor of your car’s body. This is because as per the laws of reflection of light, it diffuses into many directions after being reflected off a wavy surface. But on a plain and polished one, the reflection is much straighter and compacted, thus increasing the shine.
How is wet sanding done?
In usual cases, cars are painted with a primer, a base coat and a clear coat. But to do wet sanding, there need to be multiple clear coats to bear the brunt of the sandpaper and not to scrape off too much to reveal the base color.
Once the pain dries, auto restoration technicians start on the sanding process with a special type of sandpaper with suitable abrasiveness so as to not leave any marks and scratches. To avoid any further chances of scratching, the sandpaper is made moist with water enough to be used as a lubricant.
The wet sanding process needs to be repeated multiple times, depending on how the outcome is every time. In the end, after a process of bluffing and polishing gaze, you can even see your own reflection in the car.
