I am fixing up a Gottlieb EM for a friend on a budget. The legs were badly rusted, well beyond saving the chrome. I decided to try Dupli-Color "Chrome" spary paint from Walmart. I first sanded the legs with 150 grit. Then cleaned them with lacquer thinner. Next I sanded them with 220 grit.
After cleaning again, I applied a scratch filling automotive primer I had left over. After sanding smooth with 320 grit, I painted them. Although not as bright a real chrome, they came out surprising well as shown in the pic. For "player" games and/or a budget, it's an option.
