I use Venetian Turpentine instead,for the anti-bacterial properties and stand the tin in some hot water first to thin it out. I put it on before he's turned out - in the morning during the winter and of an evening in the summer before he goes back to his field.
Can I please just scream - CAMROSA!!! it is absolutely amazing stuff - doesn't hurt, creates a shield and heals at the same time. Does not stick to anything.
I have never come across anything like it.
