Dry guide coats

Dry guide coats (control coats) are coloured powders or light coatings used to make scratches, dents and uneven areas clearly visible during sanding. They are applied over fillers, primers, paint and gelcoat to highlight high and low spots and guide you through the sanding process. Most applicators have flexible edges for use on contoured surfaces, making guide coats ideal for automotive bodywork, marine gelcoats and industrial refinishing. Control powders sit in low areas so you can see exactly where more sanding or filling is required. Using a dry guide coat is a simple, low-cost way to avoid hidden surface defects and ensure a smooth, even substrate before primer or topcoat. Choose a contrasting colour for maximum visibility and faster, more reliable finishing results.
