Query: Amazing stuff!

Went on easy and lasts FOREVER! As I write this review (4/2012) 303 has been protecting my fabric convertible top since Spring 2011. Water still beads up all over! Another reviewer complained of the smell but I did not share that experience. Remember it is a protector not a restorer. If the fabric is in bad shape then 303 will not work miracles. This particular 303 product is for fabric. If you have a vinyl top then 303 for vinyl is what you need. Best stuff that I ever used, very satisfied with the results.
