Spray can primer vs. AB primer

are you looking for something to spray indoors ?..there are AB primers available

I've used spray cans before (not for AFV modeling). Their spray patterns were wide. That's why I'm worried about using spray primers...

I don't know what the size of a spray can nozzle is, but it's all use to prime my models (1/350AFV's).  I use Rust-o-leum  Automobile Primer, Light Gray. I've never had any problems with it.  It gives a nice coat, with no obscuring of details.  Hope this helps
