Polyester Hi-fill Primer Question

Giving my '70 Chevy C10 a full repaint, int and ext.

I'm using Eastwood's Contour Polyester Primer-Surfacer. Mostly over sanded OEM paint, but a few small spots of bondo and bare metal and a few new parts (hood, front fenders, tail gate) .
https://www.eastwood.com/eastwood-co...-surfacer.html

I used 2 gallons of primer, 2.5 tip, 20oz primer, 1oz hardener, 3 oz acetone, 80 degrees, 15% humidity. Sprayed on nice. But, I ran out of primer before giving everything its first coat.

2 questions
a. will it hurt to give panels their second coat a week after the first coat dried?

b. should I sand the first coat before applying the second coat of primer?

Follow the data page, if maximum recoat time is exceeded then you at least need to sand the overlap to finish the first coat.

A week will be outside the re-coat window. I'd be sanding it wherever new material will cover the first application.
