well you are going about it the right way.. now, the surface rust that you are describing may be different from what im thinking. if its only sat a couple days i guess D/Aing it will be fine.
At the moment im restoring a 66' GTO that was repainted about 10 years ago maybe less and when i was stripping the paint i realized that there were specs of rust all over under the paint. they werent visible from the outside but this car was also garage kept since the repaint ten years ago and hasnt seen heavy rain since.
The second i saw the rust dots i figured someone just D/Aed the surface rust and painted over it. So if i were you i would atleast take the 5 minutes to get that little bit of rust of with naval jelly or even metal conditioner will work on it and if ur using and etching primer d/a the baremetal again after u use the naval jelly. then spray and you will be good to go.

I use an epoxy etching primer on the bare metal then my
normal 2k primer over that.
I use to use a single stage etching primer first but my
2k primer didn't adhere very well and I was told to always
use an epoxy etching if your topping with a epoxy primer.
