We just did our first "no fit" division at our County Fair. We showed one in the Fit division and one No Fit.
First off, find out EXACTLY what "no fit" means at your show. I was under the impression it meant that we could not put anything on the steer. After asking, I found out that it meant NO ADHESIVE. That's it......we could put anything in his hair we wanted, as long as we didn't use any glue.
If I would have found that we couldn't foam, I would have put "hair putty" in his legs the day before the show...maybe even at home. As long as you don't soap it or put hot water on it, it will stay there. Then the lower leg hair would have stayed up. I know that some people will say that is cheating, and maybe it is...I don't know.
I guess it comes down to the steer anyway. He looked better fit than 3/4 of the fit steers did, and that is really due to the work that went into him at home. VC is probably giving you the best advice...get to brushing.
