What is the generally accepted limit for paint thickness?

The generally accepted limit for paint thickness is often around 15 mils. Keeping paint thickness within this limit is crucial for achieving an optimal finish and ensuring proper adhesion. Excessive thickness can lead to issues such as poor curing, increased susceptibility to chipping, and a greater chance of runs or sags in the paint.

In automotive painting and refinishing, maintaining appropriate paint thickness also contributes to a better overall appearance and durability of the finish. When the thickness exceeds this accepted limit, it can also create problems with the paint system interactions and can affect the performance properties of the paint.

While other options represent thicknesses that are higher than what is typically accepted, sticking to around 15 mils helps to ensure that the finish remains in good condition over time and performs as expected in various environments.
