I have the Diamond Shield logo on my coach -- my coach is a 2007 Newmar. If anyone has advice on how to remove that stuff from my coach, I would appreciate hearing (reading) it. There is mold under the Diamond Shield....I contacted the company--their reply was that I could pay $1,000 for removal of their defective product from my coach and the installation of a wonderful brand new product on my coach -- I don't think so. I simply do not trust a company that puts out a defective product and refuses to stand behind their product.
