With a sponge, apply a light coat of glass primer along the edge of the quarter glass (A), front seal (B) and rubber dam (C) as shown, then lightly wipe it off with gauze or cheesecloth:
With the printed dots (D) on the quarter glass as a guide, apply the glass primer to the upper, lower, and rear corner portions of the quarter glass.
Do not apply body primer to the quarter glass, and do not get body and glass primer sponges mixed up.
Never touch the primed surfaces with your hands. If you do, the adhesive may not bond to the quarter glass properly, causing a leak after the quarter glass is installed.
Keep water, dust, and abrasive materials away from the primed surfaces.
