I have a question for anyone who might know..how thick should the consistency be of the bleach/developer for when bleaching knots.

In general, my confusion over the knot bleach process is whether any or even just a tiny bit of the bleach/developer should actually leak through to the hairshafts. Or should the bleach/developer be thick enough so that absolutely none of the bleach will drip down to the hairshafts, meaning that only the bottom of the knots near the lace would be bleached and not the top of the knots near the hairshaft?

I have Debbie's knot bleaching kit and I believe that the instructions say that the bleach/developer should be the consistency of whipped cream. I tried applying cool whip whipped cream to the bottom of an old hairpiece to see what it would be like. Some of the whipped cream dripped/leaked onto the hairshafts though.

Sp does anyone have any suggestions on what the consistency of the bleach/developer should be like for when applying to the lace for bleaching the knots?

Any ideas/suggestions would be greatly appreciated.
