Thanks for the help.
After ordering the stuff (of course), I read that dye prep is for undyed leather, whereas deglazer is for re-dying leather. Is this just a marketing gimmick, or should I order the deglazer?
Also, what can I do about the frayed edges? It seems like the tragacanth and wood slicking stick would work on the strap, but I don't think it would work on the joints. Would my best option be Tandy Edge Kote? http://www.amazon.co...1/dp/B004303LMC
If so, then should I apply the Edge Kote after I dye, but before I apply the gloss? Do I need to get an edge slicker for this, or can I get away with using something else?
