Lincoln’s leather dyes are far superior to Any others I’ve tried. They are very colorfast, and resist sun fading. Fiebings dyes are much weaker than Lincoln’s, so if you are used to using Fiebings you may need to thin Lincoln’s a bit. It is harder to find than Fiebings, but is readily available on line. Both the local shoe repair shops use Lincoln, and swear by it.
