Normally I would just use rain maker as a hoof conditioner but someone recently told me to stay away from pine-tar based products as they will actually weaken the hoof wall. I checked out the ingredients in the Farnam rain maker... pine tar is one of the first ingredients listed. I also have a product called "Farriers Hoof Oil" (it comes in a simple blue and white container) but that is more for soreness after being shod.
