My horses never seem as shiny as the rest of the show horses. I think they look great until I get to the shows and we are outshined. So help me out please. What are some good tips and tricks to really get that shine, particularly on a gray. I've found some things online, including olive oil, cod liver oil, doing a hot oil treatment, several different types of coat sheen sprays. What works and what doesn't? And what is likely to make the dust stick?
