Can I safely lay down one (or even two coats) of primer and then do the top coats in the same session? If I leave (say) 10 minutes between coats, I have plenty of time to apply all necessary coats within the recommended recoat window of 1 hour. All paint would be Rustoleum, so there should not be compatibility issues. A related issue is spraying a shot of clear or base color to seal the masking tape before applying a second color coat. I would certainly *want* to do that all in the same session. I asked Rustoleum directly about this and they seemed to say this was OK to do as long as I stay within the 1 hour window, but their response was a bit cryptic so I'm not quite sure what to make of it.
