I use sheeps wool for my application. Of course, I trim each piece of wool to a low nap. I also run my hand over the piece before using it to make sure all the loose fibers are off. Plus, I have poured some Tan Kote into my Fiebings antique paste and shake well before use. After my paste dries, I use sheeps wool and tan kote to remove the excess paste.
As for Chan Geer's or Kris Tanner's finish is commonly referred to as the Sheridan Finish. I am sure you can find the recipe on this forum if you do a short search.
I also currently use Clear Lac, Neat Lac, Wyosheen and Bee's Natural RTC finish. They pretty much all work some what the same. Except for Neat Lac, there is no substitute. As for the RTC, it is a great alternative to the fumes the others create especially in a regulated low VOC state.
