How to Keep a Pinball Backglass From Cracking & Peeling
- 1). Spread some old newspapers onto the floor.
- 2). Remove the backglass from the game and carefully set it down, painted side up, onto the newspapers.
- 3). Spray a slow, even coat of Krylon Triple-Thick onto the backglass. Triple-Thick is an aerosol spray product that will create a thick, lacquer-like film over the entire backglass.
- 4). Immediately cover the wet backglass with a layer of plastic wrap (such as Glad ClingWrap). Smooth out all creases in the plastic wrap.
- 5). Push down gently on the wrap over the peeling areas of paint. The goal is to get the flaking paint to lay down flat rather than continue to curl up.
- 6). Let this sit overnight until the Triple-Thick is completely dry. Do not try to remove the plastic wrap prematurely.
- 7). Peel off the plastic wrap. If there are parts of the wrap that you can't tug loose, trim them off with a straightedge; don't try to force it to peel off.
- 8). Spray another even coat of Triple-Thick over the first coat. Allow the product to dry for 30 minutes.
