I just bought the Meguiar's 2 step leather conditioner and cleaner. The guy at the store said it would work on my vinyl as well. I'm sure this question has been asked before but is thist true.

By the way they didn't have Vinylx

 

have not heard that it works on vinyl too... not even from meguiars-

i would use only vinyl products on vinyl... vinylex is my first choice, but 303 works well too.
