Question about bondo usage on car

[AgaBoogaBoo]

I'm fixing up some sections of rust on my car and have a question about bondo. If I get ambitious enough I'm going to end up sanding my whole car down and having the whole thing repainted after I prep it myself so the colors all match up accurately.

If I leave the bondo exposed without any primer/paint to cover it and it rains outside, will that be an issue at all?

2nded.

In that case should I just spray some primer/paint temporarily while I work on prepping the rest of the car?

Bondo degrades quickly if left unprotected, IIRC.

Hit it with primer before you go to work on the rest of the car.
