"I had a lot of graffiti tagging on my walls at my corner house. I was sick of wasting money on removing the graffiti and recurring every month. Dr. ScratchLESS explained to me a service they provide for a coating over the wall, once applied all I needed was a 500ml spray bottle and water hose and the graffiti tagging dissolves instantly. This coating lasts 20 Years and I have sprayed this solution 5 times and now there is no more tagging. Thanks Dr. ScratchLESS you're the best".
