A clear coat is the final coat of paint that applied to the car, going over the epoxy and base coat.  It’s a transparent, tough, and glossy coating that adds more than just shine to your car. It’s a protective layer against abrasion, scratch, dents, and corrosion to the car’s exterior

When it comes to car painting with 1-Part Paint, clear coating is almost a necessity as 1-Part Paint itself has low glossiness and resilience.

However, a clear coat becomes optional when it comes to 2-Part Paint. Why clear coat isn’t necessary for 2-Part Paint? Here’re the reason:

High glossiness and color retention

Because of the different chemical compounds, 2-Part Paint is able to give a high gloss attractive finish which can withstand the impact of UV rays that causes fading.

Contain hardener

The hardener makes a fully cured 2-Part Paint forms a very hard, durable, and hard-wearing surface that provides enough protection against abrasion, stains, and scratches. 

Although the clear coating is unnecessary for 2-Part Paint, you can still spray a layer of clear coat on a 2-Part Paint to achieve the mirror-like finish and extra protection, the decision comes down to a matter of personal preference.

However, there are a few things you need to keep in mind. First, be sure to use a high-quality clear coat that is designed for automotive use. Second, make sure the surface is clean and free of any dirt. And finally, be sure to follow the instructions on the can of clear coating carefully so that you don’t damage the surface or the paint job.
