Wow..no offense but lets get back to the topic. If you have a difference of opinion fine, everyone is entitled.

i forgot to add to my earlier post that when you start off do it on a non sensitive area first. Experiment with different heights and speed of drips and colors. When you have found the right combination then you can move to more sensitive areas. Save the super sensitive areas until you have some more experience. Other than that just be safe and have fun!
