High build primer-surfacers

[belaw]

I'm hoping someone can educate me on what options I have for a primer surfacer.

Here's the situation: I'm planning on doing the body work through the primer stage on my 40 myself, and then having someone else do the paint work since I don't have access to a full paint booth or a positive air pressure mask. That rules out most of the 2k primer surfacers that everyone recommends, as they are all iso based.

Are there any quality high-build primers that are safe for normal use? If I have to use a sealer coat I'm willing to accept that as a cost of doing business.

Also, I'm planning to top coat with basic old-school acrylic enamel.

If you use high build primer check the nozzle size some high builds require a bigger nozzle opening or it will constantly plug up on you and spray like stucco.

about any 2-part catalyzed surfacer primer is safe for u're condition given good enough ventilation. i use k36 at work daily & don't even use as much as a dust mask. open the doors & use a box fan to help draw it out & keep the air pressure low enough to keep the overspray out of the air. if u have any bare metal, be sure to put down some epoxy primer first.

The booth isn't so much a condition in priming because you would go through and sand down all the nibs and dirt anyway even in a booth. The major concern is airborne paint hitting other people's cars, your house, etc.
On the health side, few painters use positive pressure systems. Even regulation air force painters spraying advanced coatings only wear facial protection in addition to normal vapor masks. This is the same mask, minus the face protection, http://www.tcpglobal.com/3m/ItemDetailKit.aspx?ItemNo=MMM 7192 and a pack of organic vapor cartridges($5), again what the military deems safe.
