Thank you for such a quick response. Just to give a bit background...we lost a child in our family to an drug overdose and started a Foundation (Nikki Perlow Foundation) in her memory to help young people like Nikki Fight the Disease of addiction.

We look at this from different perspective in that we launch projects to demo that recovery is achievable with proper treatment. Our "to be" project "Forest of Hope" will celebrate those who have conquered their addiction by painting the trunk bark of mature trees in a forest so the public can see, learn and experience a magical walk through the forest as each tree will share a recovering addicts journey/story to success.

What would be so helpful is a statement that using the proper water based paint will not harm a mature tree.

 

Greatly appreciated....also Google Forest of Oma in Spain (or go to link below) which is  similar to our project and a national/international destination tourist attraction.
