Product Description
SEM 38203 Guide Coat in Black is a professional dry powder aerosol used to reveal surface imperfections during sanding in automotive body repair. Applied as a light mist over primer or filler, the guide coat fills low spots and highlights scratches, pinholes, and waviness as the surface is block-sanded — an essential diagnostic tool for achieving panel-perfect flatness before topcoat.
Key Features:
- Surface Imperfection Detection: Reveals high/low spots, pinholes, and sanding scratches in primer and filler.
- Dry Powder Formula: Dust-like application that sands away cleanly without contaminating the surface.
- Black Contrast: High-visibility against light-colored primers and fillers for easy defect identification.
- 16 oz Aerosol: Quick, even application over large panel areas.
- Professional Standard: Essential body shop tool for verifying surface quality before topcoat.
