Go on to the Ecker's Corvette parts website. They have a convertible top protector recommended by Hartz convertible top manufacture. I have used it for years on my Corvettes, and now on my Crossfire. You just spray it on every 6 months and it will protect the top from the sun and rain etc etc. It is worth every penny. Especially when you see how the top beads up when it rains. Just my 2 cents!
