How is this at all pinball related? Well, Krylon Triple Thick Glaze spray paint has been the "Go To" method to "preserve" the paint on backglasses from years past! It stops the flaking.
From the www.USAtoday.com
About 98,400 cans of both Krylon triple thick glaze and Krylon crystal clear are being recalled because they are leaking. Its a potential fire hazard, and we all know what pinball machines hold up to fire.
