I have a Gottlieb Big Hurt in like new condition that I purchased. The wire ramps have begun to chip and I would like to get them refinished. The original finish was brass plating, but I am wondering if powder coating or chroming would hold up better. I would like to keep the game original as possible, but I cant seem to find anyone does brass plating around my area. Also, is there someone that performs ramp refinishing in a timely manner?
