why is it a pain, i find it easy, but i dont use that formula. i use: 3 Cups Calhoun Soft, 1/4 Cup Softener, 1 Cup Super Fine Salt. i weigh them out and get very consistent results.
when you fill your injector, cycle it 2-3 times before you fill your mold. place the injector so the tip is at the bottom of the plastic, fill, then discharge it, fill it, discharge it, fill it and discharge it. that will stir up the flake and salt good.
