But that is a minimum under ideal conditions.
I strongly suggest you always wait an hour because none of us
spray under ideal conditions. But you're also not suppose to let base
sit longer than 24 hrs before clear, so somewhere in the middle is fine.
Check the tech sheet for your brand, some brands may be different.
If the black is a urethane, I would wait 3 hrs before clear.
When striping with base coat I have been able to lightly sand the tape line after tape
is pulled with a fine grit paper like 2000 just enough to soften the sharp edge the paint leaves. Don't try to level it, just soften it and the clear will do the rest.
Like I said, I always plan on two sessions of clear coat to level it completely.
Thank you sir
