One of my winter projects: I am going to have Powder Pro turn my rusty old galvanized plow anchor into a shiny new white anchor for ~$500. Read the process. It will have a thick coat of primer (which is powder) and 2 thick coats of single stage powder. I rarely use the anchor, mostly docking or mooring. When I do, it is in a mud or sandy bottom. Beats buying a new stainless anchor of that size. The thing has to weigh over 50#. Its a beast.
