I'm trying to coat my hinges and hood latch using a "parkerizing" processes - zinc phosphating. I also understand that many of the nuts and bolts are magnesium phosphate. I've read up and it appears that the process is easy once you've cleaned the part. Palmetto Industries was mentioned several times as a great supplier, so I called, and then emailed Scott. I received an email response stating that unfortunately hes has gone out of business. Does anyone have any experience with another supplier?
