I have used that pretty extensively when I am doing original fasteners and small brackets. It takes a little finesse to make the parts come out looking like new. A bead blaster will be a big plus, as the parts you want to plate have to be insanely clean to achieve a nice finish. I use a model train transformer instead of the battery that came with my kit and tend to overplate slightly then gently brush the parts with a brass wire brush to get the finish to appear as bright zinc. It isn't quite as nice as the parts I actually have cad plated, but it itsn't far off and is much much cheaper. If you are having a car judged, it will get you many fewer deductions than a can of the zinc spray paint. The corrosion resistance is probably only as good as the original plating, but I don't usually go through the hassle of replating original fasteners on a car I plan to drive through puddles.
