I'm doing a little body repair on some aluminum panels. Being that the project is outside, and having little time to work on it here and there... after completing a section, if I simply sprayed some spray paint over the body filler and surrounding area, would that be enough to protect the body filler until it was ready for real paint? The project is on a timeframe and I'm very limited where I can work on it. Thanks for your time!

I would use epoxy primer to waterproof the filler.
You can now buy epoxy in spray cans, or you can
mix up what you need and roll/brush it on using a
throw-away trim roller. Then block sand the brush
marks away and you're ready for the next step.

This is the method I use as well, mainly because I always have epoxy on hand.
Spray the areas or panel with a quality 2 part epoxy or as stated above it can be rolled or brushed on.
If your panel is done as far as prep work goes you can also seal it with reduced epoxy primer.

I am curious as to why Primer would need to be protected from a little rain water or morning moisture when its OK to Wet sand.

i believe the post is about protecting body filler not primer,

i would still go with crash wrap, the epoxy is not made to be exposed to UV and some primers fail just after a few hours in the sun. you are stating this is a outside project.

the epoxy will fail i advise against it

You may be right on that Dave.
I don't know about other epoxies but ********** has UV inhibitors and is good for a couple of years outside.
