It's 40 degrees right now and sunny. The high today is 58.

Am I going to have any trouble applying ZFX-enabled Z2 and/or Z5? Should I give it longer than the recommended 20-30 minutes?

Thanks!

 

I've applied Zaino in the mid 30's before with no problem. It may take just a little bit longer to dry but not much with using the ZFX.

 

Definitely give it longer - maybe 2-3 hours if you're close to freezing. Don't apply at all if you're below freezing. At least, that's my personal experience. Try applying in the sun if possible as that will increase the surface temp of the car, at least.

The most truely temperature dependent car detailing stuff I'm aware of is leather conditioner. It'll stay on the surface and help protect, but won't actually condition the leather if it's not 60+ degrees inside the car in many cases.
