The nanocoat product that was applied to my brand new shower screen did not work. After about 3 weeks use my shower screen was densely stained from minerals in the water - worse that if it had not been applied. Rang [Redacted due to mentioning name] who has failed to turn up to rectify. I have since removed the nanocoat surface and my shower screen is now back to new again. Very disappointing product and service.
