Dry Guide Coat is used to identify surface imperfections such as pinholes in body filler and deep scratches in primer. Unlike liquid and aerosol guide coats, Dry Guide Coat requires no masking before use, and there is no dry time after application. The dry solvent-free formula doesn't clog sandpaper and delivers easier cleanup.
Used in the 3M™ Dry Primer Sanding System. When sanding body filler, Dry Guide Coat helps technicians ensure the filler is flat (no ripples) and that the body styling lines and contours are correct. It can also be used to make sure the entire primed area is sanded prior to applying a top coat.
