What could be a result of not using a strainer when filling a spray gun?

Not using a strainer when filling a spray gun can indeed lead to inconsistent paint texture. A strainer is essential for filtering out impurities, debris, and clogs that can occur in the paint. These materials can originate from the paint can, the mixing process, or even from the spray gun itself. When these contaminants are not removed, they can lead to uneven distribution of the paint as it is sprayed, resulting in a texture that may appear rough, bubbly, or uneven.

Inconsistency in texture affects the finish quality of the paint job, making it appear less professional and potentially requiring additional sanding or recoating to achieve the desired smoothness. Thus, using a strainer is a critical step for maintaining the integrity of the paint and ensuring a high-quality finish.
