Always had decent results with care and day supreme coat, but for blinding shine, supreme products sparkle spray is magic. I have to say, I now just use pig oil on manes, tails and legs to stop mud stick and it makes them very soft and shiny.
Do any coat sprays actually help lift muck and grease from the coat? I think because my horses are living on a dirt pen and well eaten down field at the moment they are utterly filthy. Unless we get an Indian summer I'm not sure if I'm going to get chance to bath then again...
I'm probably just going to have to get busy with a body brush really.
