Paints are a very delicate thing to maintain and the quality of the paint depends on various materials such as chemicals. How good the paint will be that mostly depends on the chemical.

Do all brands use good chemicals in the paint? No! There are few brands that take care of such issues pretty nicely. Brands like KBS, MAGNET paints, Por 15 and other reputed brands like these make sure that the paint they produce is top-notch.

So the advice is, always go for well-known brands. Though they are a little expensive but will deliver proper value for the money in the long run. Not only that, with a good brand you will get a long warranty and that means there is no chance at all that you will end up wasting your money. Plus, if anything goes wrong customer services are there, well-known brands come with great customer service.

The Chassis Color Paint

There are various color paints available in the market, mostly solid colors. If you are looking for a suggestion about picking the color, we would say go for the black paint. Because this color delivers superior performance.

Quantity

The obvious thing, you have to the quantity. How much paint you will be needing that depends on the size of your vehicle which is why it is mandatory to know the paint coverage per square feet. That being said, the quantity won’t have to be accurate, you might be needing more paint because sometime you will need to give a double coating on the chassis.

VOC Compliance

The full form of VOC is Volatile Organic Compounds. In paints, there are some toxic chemicals that can cause several health problems such as throat irritation, headache, dizziness, nausea, liver damage, fatigue, kidney failure, skin allergy, eye irritation, etc.

So inhaling the paint is the last thing in the world you would want. However, several researchers were conducted on this, people have tried to make paints better so that they don’t harm. And so far they are successful.

The Environmental protection agency, occupational safety and health administration regulates the VOC. And it is your duty to consider the VOC compliant when you are purchasing chassis paint. Go for the lowest VOC level, the lower the VOC the more environmental-friendly the paint is. And ignore chassis paints that come with lead, that can cause health issues.

The bonding

Whenever you paint the chassis you want it to last for a good time, right? You cannot judge the bonding of paint until you don’t apply it. However, the symptoms of a good paint bond are, the paint will get absorbed nicely on the vehicle and after it gets dry, it will form a strong bond. You will feel the bond once you tough the paint after drying up.

How well the bonding would be that depends on the applying process as well. If the paint is not applied well, it wouldn’t be able to form a good bond that doesn’t matter how better the paint is. So you need to know how to apply paint properly as well.

Additional features of Chassis Paint

As we said, there are a lot of chassis paints in the market and they come with different extra features. For example, some works best in humid areas, some are UV resistant. So you need to determine which features you actually need and then you have to act.

If you are living in an area where humidity is high, then go for paint that can tackle high humidity. If you think the truck frame will be exposed to sunlight, then go for UV resistant chassis paints.

Before you purchase paint, think from all the areas, think about the pros and cons of the product. The more you think, the more chances there is that you will end up with a good chassis paint.

Importance of Chassis Paint

Why the chassis of the vehicle needs paint? There are several reasons why you should paint the chassis of your vehicle. Take a look below!

Rust and Corrosion

What is the core of the vehicle that holds the vehicle? The chassis! It is exposed to every kind of external threat. Dust, water in rain, ice, etc. all these can cause the chassis to rust or corrode badly. And that will shorten the lifespan and weaken the chassis, these are something that nobody wants. You can save the chassis from all these by just painting it.

Maintaining the value

There are some people who care about the resale value of the vehicle. How high the value of the vehicle would be that depends on the condition. And when the core or the framework of the vehicle is corroded, rusty and ugly, no one will give a good value for sure, even you won’t if you are the buyer. With the right paint, you can get rid of all these.

Strength

Once the chassis of a vehicle gets rusty or corroded, that gets very weak. We have mentioned this above as well. And during that rusty and corroded condition if the vehicle encounters an accident the chassis will not be able to withstand the hit. That means, your entire vehicle might turn into a disaster. Chassis paint will keep the chassis stronger by eliminating rust and corrode.

Engine damage

Rust can spread. If you haven’t taken good care, then the rust can spread to the engine as well. Not only engine, transmission, gas tank, driveshaft, etc. can get rusty. Once the transmission gets rusty, you won’t get good driving experience, the rusty tank will leak gas, the rusty engine will get damaged with time. This means, to save a few bucks off the chassis paint can cause you to sacrifice the entire vehicle.
