I’m sorry about yet another negative comment, but Vallejo primer doesn’t work very well. It has not bite, you need something like Mustang Joe is recommending.
Too bad about the Mr Surfacer being out of stock, that stuff works very well.
I’ve settled in on Stynylrez primer bought through Amazon since moving to acrylics, very happy with it but I do thin it a little bit ( I guess most people don’t but it’s a bit thick to me). I also scuff larger surfaces so probably most primers would work pretty well given that. But even where I don’t scuff ( small parts on spru trees etc) it’s been fine.
I also tend to heat set it fwiw.
Suggestion here. I would scuff up the larger surfaces and what you can get at on the smaller surfaces. Spray your primer and heat set it, see how that goes for you.
I scuff my models with those foam fingernail pads the ladies use on their nails, my wife had several around here so I hooshcowed one and liked it and used it to death. So I went to Sally’s beauty supply locally and bought a couple of the fine ones. A gray one and a white or creamy colored one. They seem to conform well and not wipe out fine details. When I painted 1:1 equipment final scuffing was always with scotch pads fwiw. I wouldn’t up and quit on the Vallejo primer, try what I’ve said above and see how that goes for ya. Course I’m saying all this as a Stynylrez user and convert from solvent based primers and paints too for that matter…
My go-to rattle can primer is Rustoleum wet/dry sandable primer. I’ve got it in 2 colors - white and grey.
Do you feel the Rustoleum primer gives you a scale coating of paint and good leveling ? I’ve used Krylon, the light gray was good ( thin coats and smooth), especially if the can was heated in hot water. The red oxide I liked but the coats to me were too thick IMO, great color though. Course a lot of this has to do with the scale of the model too, at the time it was 1/64th scale. This was about the time we lost Floquil.
LOL!! No worries, its not like I bought a lifetime supply. Vallejo offers the ability to not need to thin, which is why I wanted to try their products. I played with a couple of test parts last night with the black primer and shot the 3 colors for the main body (Dark Green, Ocean Grey and Med Sky grey). Not horrible, I will need to make sure to do a decen job with the white mottling (not sure what its actually called) as the black primer turns the shades a bit dark.
I’m in an apartment, and rattle cans tend to stink up the garage a bit more than I like. Its why I am working with acrylics as well. Dont need neighbors getting high off my fumes… although they are college kids so maybe I can charge them to fund more builds 
I’ll have a spray booth up and running in a few days, but even then I think the rattle cans may be a bit much.
Understood re the stinky oil-based paints.
The Stynylrez mentioned above is water-based and oderless. Like omg, it is my go-to primer now. A fellow forum member sent me a bottle a couple years back, I’ve never looked back.
I failed to mention that my problem with Vallejo primer is it hasn’t adhered very well for me. Otherwise, Vallejo is my go-to paint.
If you’ve got it routed to the outside you’d be surprised how quickly the odor dissipates. I shoot lacquers inside my spare bedroom with a paintbooth and inside of 10 minutes the odor is all but gone. I do understand your dilemma though as before I had the booth I had to use acrylics exclusively.
Yes, because over the years (20 years in fact), I’ve learned and mastered on how to spray in several light coats to give me the best results. As far as Krylon goes, they’re long banished from my stash of rattle can paints. Had a few model kits ruined by that piece of garbage brand of spray paint over the years. Never again…
