Guess it depends on where you are applying it. For the tail I do little parts in the hair and dribble the mtg on and rub. Keep shaking the bottle it settles really fast. I start at the top doing little parts rubbing it into the tail bone all the way down to the tip of the bone.
Then I just brush it really good.
For the mane I dribble it along the crest and rub it in really good. Again finish with a good brushing.
I don't do any wrapping.
For a rain rot or skin problem I just put a little on the spot.
