What is one of the consequences of using an incompatible topcoat with the underlying base coat?

Using an incompatible topcoat with the underlying base coat can lead to possible lifting or wrinkling of the paint. This occurs because the solvents and chemicals in the topcoat can react adversely with the base coat, causing it to soften or dissolve. When the base coat is compromised in this way, the integrity of the paint layer is affected, leading to visible imperfections like lifting or wrinkling.

This critical aspect highlights the importance of ensuring compatibility between different paint layers in automotive refinishing. Proper selection and testing of products is essential to achieving the desired finish and longevity of the paint job. The other outcomes, such as improved durability, faster drying time, or uniform color compatibility, generally stem from using compatible products and would not apply in this context.
