I have a bottle of Createx ilustration. That is very thick and difficult to come out of the bottle. Did not dilute it, but I do intend. I have a few ops. 1. water 2. colden extender 3. isopropyl alcohol 4. 4012 I know that 4012 is the most obvious. But I want to keep the shelf life as long as possible. What are your thoughts about this.
