I just want this stuff to stay on the paint forever! Especially when it comes to fighting swirl marks Z5 does wonders!

With that said, I want to know how long this stuff stays on my a paint and how long until the swirls start coming back?

 

Swirls coming back are mainly caused from what towels and wash mits you are using. Using the right ones will not cause new swirls. Zaino is meant to be used once every 4 to 6 months as far as the polish goes, but using the Z-6 is the real key ever so often. Z-6 helps fill swirls and scratches also.

swirls happen!!
no matter how careful you are you will get them, imo.
my car is over two years old and i can finally see swirls. by taking care of your car, you can delay the swirls- but i think it is almost impossible to completely avoid them.
i plan to swirl remove in a few months and expect that to last another couple of years or so...
since the zaino swirl "remover" is really a swirl filler, the swirls are not gone. at some point you need to remove the swirls (which will probably remove all zaino too) with something like the 3m swirl remover.
