    “We have been using your OptiShield product now for the past three years and I must say it’s a great product. It takes about half the time to spray the material comparing to the Black Mac, the guys love using it because it’s not a hazard to their health and the material still looks great after two years of wear. All in all it’s a much better product and we couldn’t be happier.'

    “Overall I feel this was a good buy on the towns behalf, and I have reported this to our town council. It was costly but will pay for itself in the years to come, I appreciate your call back to ensure we are not having any issues, and really have no negative feedback for you.”
