Exactly... Use Retayne before you cut , it will set the unset dyes. Synthropol is used once a project has been completed , and you can not set the dyes, as ..if bleeding occurs Retayne will set the bleed. Sythropol will keep the suspended dye excess from "attaching" to the other fabrics.
Key to the use of both is the water temperature both require 140 degree water to be effective.
