Re: Masking questions
With masking, the first color is dyed, then the mask is applied, then the balance of the first color is removed with bleach, rinse, acid, rinse (repeat if necessary). Don't get the acid contaminated with bleach or vice-versa, or deadly gasses will be released that will literally kill you in a heart-beat.
Once all of the unwanted dye is removed, go ahead and dye it the second color. Rubber cement makes a very fine line, and so does hot-glue. They are both a bit stringy, though, so be carefull with that.
BTW, the reason for the double-dip to remove unwanted dye is because dipping in bleach works best for removing color, but will affect the next colors. Acid does not affect the next colors, but doesn't remove the dye very well. Heating to no more than 70F helps as well if it's cold where you are at. Just make sure the parts are rinsed well in seperate containers, and you'll be alright.
