When the OP mentioned a "hi gloss finish," my first thought was the stock; however, his subsequent reference to "pitting" indicates metal. It's good to know Scattergun Bob experienced such positive results with Remington's factory metal refinishing jobs.
Wood stock refinishing is a task gladly undertaken by many gun owners. Plain Jane looking stocks may be made to look very nice with the judicious application of hand rubbed finishes. Unfortunately, traditional methods can't be used when duplicating the high-gloss synthetic finishes as found on Wingmasters and 1100s. Those with the capability of spraying a similar finish may have great success. However, problems arise with Remingtons having pressed checkering. Hand cut checkering can be re-cut after spraying a fresh finish; but, what to do with pressed checkering? One can mask-off around the pressed areas or smooth them and cut fresh checkering. I'm curious, does anyone know how Remington addresses the pressed checkering with a factory re-finish?
