Central Coast Diamon-Fusion

I remodeled a bathroom and have glass shower surround. I read about Diamon-​Fusion to keep the glass from spotting. Central Coast came over quickly after the glass was installed and applied the product. They were quick, efficient, clean and professional. It’s been 2 years and the glass is as beautiful as when first installed. There is hardly any maintenance. I recently contacted the company to ask about hard water mineral buildup that was on my granite sink and bathroom fixtures. I had used many different products as well as white vinegar but nothing worked. Didn’t want to use any harsh products which may ruin the stone and fixtures. He recommended using a finely crushed pumice and non scratching buff pad which he then personally delivered to me. It worked beautifully on both the stone and fixtures. He provided great customer service even years later.
