I agree here, in the first few trial runs I made the cure would have about a years shelf life and then it would clump/brick up a bit. I added silica and that solved the problem and never seemed to change it's successes.

I've never tried the plastic bag idea like Nick mentioned, but it all still circles back to finding a company that will mix/bottle or mix/bag the cure. The place I had an agreement with backed out after the second run because the dye is like a super spreader, you don't see it but when your done your nostrils clothes, walls, counter tops, etc all turn pink and it's a bitch to get off...
