Who is correct regarding the use of a strainer when pouring solvent?

Using a strainer when pouring solvent is important for several reasons, which supports Technician B's assertion that you should always strain. Straining solvents helps to filter out impurities, debris, or particulates that may have settled in the container. When these contaminants are introduced into a paint gun or mixing container, they can lead to problems such as clogging, poor finish quality, or uneven paint application.

Using a strainer ensures that only clean, usable solvent is being applied, thus maintaining the quality of the work being performed. This practice becomes even more crucial in environments where precision and surface finish are paramount, such as in automotive painting and refinishing. Strainers come in various sizes and mesh types, allowing technicians to choose the appropriate one based on the type of material they are handling.

In contrast, the stance of Technician A, who claims that no strainer is needed, disregards the potential risks associated with using unfiltered solvent. This approach could lead to various issues that may compromise the longevity and aesthetics of the paint job. Therefore, it is essential to always use strainers to ensure the highest quality outcomes in autobody work.
