I use 303 brand products. Get some of this stuff: http://www.zip-corvette.com/ProductDetails/ProductDetails.aspx?pid={a71370ca-a260-4a3e-a75f-7bb18ab048a9}&gid={3d052aec-4b46-4bf6-bea0-6ab0f0760c01}&GroupName=303+Convertible+Top+Protec tion&pname=303+Convertible+Top+High+Tech+Fabric+Gu ard&Referer=&Alias=&ptct=SGR-SR&CTitle=&

There is a cleaner that goes with it, too. But I have never used it (have it in the garage, just not needed it yet). This protector is AWESOME !!! I can get the top wet, towel it off, and in ten minutes it will be totally dry!

I paid $24.95 for the last bottle I bought, so their price is good even with shipping. (Bought mine locally, but I moved 90 miles from that store last fall.)
