We had so many problems with the exterior upkeep of our home. The paint wouldn't stick like it used to and the algae would come back even though we power washed it every year. We found Rhino Shield by hearing a radio ad and gave them a call. They were very helpful and gave us a great price considering you will never have to paint again. They delivered on the install. Alex was excellent. Now we look forward to more time enjoying our house, and not worry about keeping up with it.
