Fiebing's is long on solvents and short on color. It sun fades like a sun of a gun, and is hard to apply without winding up with dark spots, and light spots. Lincoln's is a hundred percent better. Lincoln's medium brown can be applied with a rag, and then when still wet, wiped with another rag dampened with water ( no its not water base) but, it really works. It ages horn, and rawhide, and leather, nicely using the same process.
