I just purchased an 2008 A4 Convertible and I am wondering if I need to do anything to the soft top? Is there any type of protector that needs to be applied? Or do I just keep it clean of dirt?
Thanks

 

303 has fabric guard spray , and also ragtop works too , yes you have to clean it and put some of those spray on it
