No, not asking about relabeling! 
I've been a Zaino user for about 10 years now. But we just got a Carquest in town and I'm curious to try some of the Duragloss lineup and see how it compares.
For any who have experience with Duragloss, what would you say is the equivalent of ZAIO and Z2?
I'm just about out of Z2, but I still have a pretty good supply of ZAIO. Is it okay to use the Duragloss equivalent of Z2 over the ZAIO?
Thanks for the help!
