I just got a Havana brown horsehide A2 from Spearhead Militaria. I would like to soften it and darken it slightly and have read about a lot of different options. Lexol, mink oil & saddle soap to name a few. Any thoughts here? On a side note, if I wanted to really darken it (say to a seal color)...would dye actually accomplish this or am I just edging closer to a disaster!?
