When is it necessary to use a paint stirrer for paint application?

Using a paint stirrer for paint application is essential to ensure paint consistency and to achieve a homogeneous mixture before application. Over time, paint can settle, leading to the separation of components within the can. This separation can cause the paint to have an uneven texture or color, which would affect the final finish on the vehicle. By thoroughly stirring the paint, you ensure that all pigments and additives are evenly distributed, resulting in uniform coverage and color consistency during the application process.

While it may seem that a stirrer is only needed for certain types of paint, or in cases where the paint appears too thick, using one as a standard practice helps minimize the risk of issues that could arise from improper mixing. Some may think it's not necessary to use a stirrer at all, but skipping this step can lead to inferior results in the paint job, such as uneven color or gloss levels. Therefore, stirring paint is a vital part of the prep process in collision repair and refinishing.
