Sherwin-Williams ULTRA 7000® S66 2K Transparent Basecoat / Blender – 1 Gallon
Sherwin-Williams ULTRA 7000® S66 is a unique 2K transparent basecoat and blending solution designed for use within the ULTRA 7000® refinish system. It functions both as a transparent basecoat and as a blender to support smooth, controlled color transitions when blending basecoat repairs.
S66 provides a uniform ground coat that improves blend consistency and metallic orientation. When used as a blender, it may be integrated into reduced ULTRA 7000® basecoat color to lower pigment load while maintaining film body.
