Hello,

There is a proposal afoot to restore the cast iron markers in the Harvard
Shaker cemetery. The method they want to use is:

³We will strip all old paint and rust off with a fine silica sand blast.
Then we will etch the parts with an iron phosphate wash followed by a
stabilizing outgas to force any impurities out of the metal. We will apply
2­4 mils of zinc rich epoxy powdercoat primer followed by 2-4 mils of gloss
white TGIC polyester powdercoat finish coat.²

Does anyone know whether this approach is considered good preservation
practice?
