Yes it is. I use it pretty much exclusively now. Also, if you intend to use Tandy's Eco Flo pro waterstain, pretreat the leather with Bick 4 and wait about 10 minutes, then apply the Eco Flo pro with a sponge, blotting off the excess waterstain onto a rag. Wipe until the surface is even a looks dry then stop. Works perfect.
