I was following the "Perfect Paint" and using SPI Epoxy (with a double shot of reducer) as a sealer over sanded 2K primer. Using white epoxy as a base for SPI Orange. Ended up with 2 coats to get the white even (was also covering some black epoxy in some areas).
The roof has some moltening that I've previously seen from too heavy of a first coat of epoxy, but I know my first coat was light this time.
Not sure what caused the issue. I waited 1 hour after cleaning with SPI W&G remover before spraying the epoxy.

How soon can I wet sand to get rid of the moltening? will 14 hours be sufficient?
Do I have to recoat with epoxy if I don't penetrate down to the 2K primer (gray).
The roof is the only area with an issue the rest of the car looks great.
I'd rather not have 3 coats of sealer under my orange.
Photos are before I shot epoxy as a sealer. No photos of issue.

14 hours is plenty. Not necessary to respray epoxy unless you go through. Definitely want a uniform color under orange. The white epoxy is the most transparent, making it the most likely to get those imperfections trying to get coverage.

This sounds like you are tilting your gun on the roof, making the bottom of the spraying fan heavy. You can sand it out of the epoxy, but not with the orange base coat. I would suggest that you hold off on spraying the orange until you get your spray pattern right for the roof.
