Instructions
Clean the painted side of the pinball backglass with a paper towel dampened with glass cleaner. If the paint on your backglass is delaminated, peeling or flaking, skip this step.
Mask any score reel windows in the backglass with painter's tape.
Place the backglass flat on a level surface, painted side up. Spray the first of three coats of thick, clear glaze spray, keeping the spray can about 18 inches away from the glass and moving the spray can quickly from side to side. Apply two more coats, letting each coat dry for at least 30 minutes.
Remove the painter's tape from the score reel windows.
