A couple of years ago I mounted a velvet buck that was taken the 1st of Sept here in KY. What little hair the cape had was red summer coat. It was done on a full sneak form and the client was elated. He then took it to his business and hung it in his non-air conditioned, barely heated shop (against my advice). Friday he brought it back when he picked up a buck I had just finished mounting. The velvet buck has rust stains all along the neck muscles and in the brisket area where it had been pinned/nailed. I rarely use hide nails on any mounts but I do pin the capes in the low points until they are dry. I use regular t-pins from taxi suppliers for this or galvanized hide brads if at all. He is now wanting to take my advice and hang it in his house. I need to figure out what has rusted on the cape and get the rust stains off. The stain is confined to the pinned points. Any ideas how to get the rust off this almost slick cape? Thankfully, there are no issues with the freeze-dried antlers.
