Ok...we just picked our Sky up yesterday and one of the first things I want to do is to treat the ragtop with the RAGGTOPP fabric treatment that I bought. When we picked up our car, the top was down and looked to be very clean (I don't think it endured any weather, dirt, or dust)...or maybe my dealer had cleaned it...I'm not sure. At any rate...would it be okay to just apply the fabric protectant...or is it recommended to use the fabric cleaner first? Just wanting some opinions from folks that have already treated their tops. Thanks!
