The brush on technique the liquid lasts forever if you dispense and do not dip your brush in the bottle, The pull date is approaching on some bottles, I wonder what will be the result as it draws near? Inconsistency of the shade?
I have little plastic paint cups that I bought at an art supply store. I pour a little amount in them and only dip the brush in that container. I think the liquid gets contaminated when you brush on the zi and then dip back in the bottle. No sediments this way and the material last and lasts. A little goes a long way when you apply it properly.Hi John
What do you mean exactly when you say dispense and not dip, as in do you mean you drop the liquid with a dropper onto the brush?
Thanks in advance
