Billy, they send you a copy of the rules with the application. You can probably get the application and rules off their website. I just get my renewal in the mail every year, so I'm not sure.
Gilley, the buyer I worked for years years ago used to wash those in something to get some of the rust off the hair. If I'm not mistaken it was bleach water. He'd skin and scrape, then wash in a bucket of bleach water, then clean water. He's then dry the fur and stretch.
