Zinc plating Parts that should and should not be plated

Updated: 2009 Jul 22

You can certainly plate anything you want to, but some parts will lend themselves to better results than others. In my experience, it is difficult to get good results with parts that have seams or joints. This is because it is very hard to thoroughly rinse all of the acid from the etching bath prior to plating. The result is that the parts will corrode very quickly right where the joints and seams are located. The same is true for pipes, tubes, and holes. If they don't get rinsed very well, corrosion will begin there very quickly.
