Buying Guide – Best Chassis Paint

Single-Stage versus Two-Stage Coating

Many DIY painters are confused about the Single-Stage and Two-Stage coating. As you should know that there are a few key differences between Single-Stage versus Two-Stage coating. Let’s explain…

As the name suggests, single-stage coatings are applied only once after you have used the primer. This type of coatings will come with a glossy finish.

So, you will not need to apply another round of clear coat to make it glossy. It will automatically be a glossy finish.

In the case of Two-Stage coating, the color and the clear coat are not mixed here. After applying the primer, you will have to apply the base coat.

Typically, the base coat would have a matte dull look. So, after the 1st stage of the coating application, you will have to apply the clear coat separately in the second stage to attain the glossy finish perfectly. As a result, it is known as the Two-Stage coating.

Solvent versus Water Based Auto Paint

There are a few big differences in solvent-based vs. water-based automotive paints. First of all, solvent-based paints come with toxic chemicals that are harmful to both the environment and the painter.

Solvent-based paints are also known as ‘Alkyd’ or ‘Oil based’ paints. So, it might deliver a durable coating but it is not good for our health and the environment.

On the other hand, water-based paints are much more environmentally-friendly compared to their counterparts. As a result, it is the best decision to use water-based paints whenever possible.

It is not only good for the environment but also not that harmful to the health of the painter. So, even if the water-based paints are pricey, you should go with them.
