Anything we value is worth protecting.

This applies to just about everything in our lives, whether it is our loved ones or a job that we’ve worked for our whole lives. It also especially applies to our assets – expensive possessions that cost us a lot of money to acquire, and which we use day-in and day-out. One example of this is our cars.

Cars are one of the hallmarks of modern life that combine functionality and style, where aesthetic is as equally valuable as comfort and performance. Hence, cars are seen as prized possessions and status symbols, meaning everyone would want theirs to look nice and stay that way.

One of the ways to protect your car — specifically its exterior — is by applying primer. Primer is a paint-like substance that is usually applied onto the metal before the finishing topcoat. This is what gives cars there smooth, a lacquered surface that everyone loves. Not only that, it is responsible for protecting your car from numerous forms of damage.

Here are just some of the reasons why primer is a necessity for your car:

Prevent rust and moisture damage

Cars are exposed to outdoor elements almost every day. Hence, it is important that they are protected from the possible damages that might result from such exposure. In particular, cars are often exposed to water and moisture, especially when used on a rainy or snowy day. In such cases, the moisture-resistant primer is incredibly helpful in protecting cars from moisture damage by adding protective layers to the exterior finish. In particular, it is very useful for protecting against the formation of rust, which results from moisture sticking to the metal for long periods of time.

Keep your car’s shiny surface

One of the primary characteristics of primer is adhesion, meaning that it helps paint stick to the bare metal. Without a buffer such as a primer, the bond between the metal and the paint coating will not be as strong, and the two will not bond well. This may lead to the peeling and flaking of the paint — and in worse cases, the formation of rust on the metal surface.

All in all, this results in long-term damage to the color and overall exterior of the car. In contrast, applying primer not only preserves a car’s color but prevents the top coating from soaking into the metal, which adds the shiny finish that you know you want for your car.

Fill in sanding and grinding marks

Over time, you may get into minor accidents, resulting in the car sustaining exterior damages. All of these may contribute to the presence of scratches that accumulate as you keep on using your car. Rather than pay a good amount of money to have these fixed, you can simply apply primer, as these may fill in the scratches and save you the need for a larger repair job.

Primer also acts as a filler for sanding and grinding marks that may be found on an old paint job, or on the metal itself. Filling in these marks also gives your car a smooth, perfect finish.

All in all, there is much to be gained and almost nothing to lose from using primer on your car’s exterior. By applying primer, you can guarantee a better look for your car, and help make sure that it stays as sleek and smooth as the day you first got it.
