Is it necessary to apply clear coat after spray painting?

[LaSophia]

After spray painting, it is generally recommended to wait for 3-5 hours for the paint to dry before applying the clear coat. If conditions permit, baking the paint in a paint booth for half an hour is sufficient before applying the clear coat. Clear coat is a type of synthetic resin, commonly referred to as a transparent varnish, composed of base materials and additives without any pigments. Once it forms a film, it appears glossy and shiny, commonly known as varnish. Here is an extended introduction to its functions: Clear coat serves as a transparent protective paint, with better hardness and wear resistance compared to colored paint, providing a protective effect. As a tactile paint, it offers excellent gloss and brightness, providing a smooth and pleasant touch. Examples include PU paint sprayed on silicone parts and UV paint sprayed on plastic parts, both of which are types of clear coat.
