Basecoat/clear vs SS/clear?

[Yossarian]

What are the pro and cons of base/clear vs single stage/clear? Can clear go over fresh single stage or is it necessary to scuff it first. Any other differences in application of the two methods?

When I do clear over ss, I wait 24 hours..no scuff, just tac

Just so I understand when I spray epoxy 1:1 not reducing always wait 24 hrs before spraying base and just use a tac rag and no wax and grease remover between epoxy and base coat

Don’t have a problem waiting 24 hrs gives it time to cure good anyway

You should wait at least 3 hrs, that's the golden rule, but that's for metallics just to
make sure the metallic doesn't get disturbed by the clear.
For a solid color I don't see why it matters.
Afterall, SS urethane is the same as clear urethane, just color added.
I hope you are talking about urethane, there's many other SS paints out there,
like lacquer, enamels, etc.
