Thanks. I have used Westley's on the gray cladding on both Sport Tracs I've owned, as well as assorted floor mats and spot cleaning, etc. without incident but I wasn't sure if it would be okay to use on the Jeep's top. The top is in excellent condition but suffers from some long-term dirt buildup. The windows are in pretty good shape but I got some Meguier's Plast-X to spiff them up. It says you can use it on convertible top windows. Now if it would ever quit raining, I can get some of this stuff done.
