Auto body repair & detailing: convertible top maintenance, convertible tops, sunbrella

Question
What can I use on my black convertible top to keep it from cracking, etc.  I do not drive it in the winter, so salt is not an issue.

Answer
well Karen am a little bit confuse do you mean cracking in the dye or sunbrella "thats the material most convertible tops are made of " most tops will turn out ok if you dye them with the right material. i have done complete interiors with a total different color and i have not had any problems ,,but if your talking about the material it self been cracked then. you would have to re do the top,  and depending on what part of the country you live in you would experience .as for myself i live in so.california we really don't have a winter.i hope this would be of some help
