This was your moment. These are the biggest questions any potential buyer will have. You leave me unconvinced you have solutions to any of the questions Thomas outlined.
1. ? Clarify "paint it on right."
2. "We made it this way. Trust us." I am not asking for the chemical formula, but seriously more evidence is required here. How do we know it works? Why does it work better? What are you doing that they are not?
3. How does another coat of paint interact with your "whitey paint" which I can only assume is some smooth polymer. Will other paints stick correctly to it? etc. People don't want "shinier" they want their wall back.
