jody111: thanks!! I will try the baby oil this weekend (thats the nearest show). I might still use show sheen on the legs, booty, shoulders, and neck but for the saddle area ill leave it and try what you suggested.
Also, I bathe the day before a show. I shampoo hair and body and rinse. I leave the mane if I braid or band it, conditioner makes it slippery. For the tail I put conditioner (human or horse brands. I use both and it all works fine) in and I work it through. The conditioner will moisturize the tail and help detangle it too. After working it in, hand pick through the tail until there's almost no more tangles (this also helps the tail grow from, oh whats the word... ummmm, its kinda like the sensation of rubbing the tail and stuff like that) anyway, then I kinda shake the tail and stand back and look. This makes small, thin tails poof up (good thing not bad lol) and big, thick tails look poofy but neat. If your horse has a big tail and this poofs it up too much just wrap your hand around the tail and wring your hand all the way to bottom of the tail. This leaves it poofy but pushes the hair together a little so that there's not too much poof. If there are spots that are a little less poofy and look funny pull the strands out away from the tail and let it fall. It should look evenly poofy. It makes my pleasure horse look like he has a fake tail in even though he doesnt. I don't brush the tail at all I just pick it and that works alone. Brushing it makes it smaller looking doing the opposite of what you want. I hope this helps!!
