If one were to use SEM high build primer are there further finish layers that must be avoided?

I don't think so but the top coat manufacturer may not back their paint. There's been some cases of that happening here. I'm referring to it delaminating they tend to say not our problem. So I would ask your local paint store about backing up the warranty.

Do any of the paint MFR's make an aerosol high build primer?

SEM is the only spray can stuff I've ever used for small spots. Only spray can primer our local finishmaster stores stock. Haven't personally had a problem from it. Used nason 2k primer over it.

If you can't spray real paint & need a true high build, evercoat g-2 polyester primer surface can be applied with a roller. of course it will take extra sanding this way, but it's thick & is a tough non shrinking filler. Basically a sprayable body filler with a few properties of fiberglass. Also not cheap & not waterproof, must be coated

What I'm getting at is wanting to do a big chunk of prep myself. I don't want to tow the shell to/from a shop to get it primed each time it needs it so I'm looking for a base primer I can work with myself.

What it sounds like is that I can use the SEM or g-2 to do the bodywork, but when the time comes a shop will have to cover that with a 2k primer and do a final scuff before spraying color.

Depending on the shop, they may want want to spray over your work, or they will tell you their work is only warrantied to what they applied it to so if the paint falls off, not there problem. Just want to make sure you are aware of that.

I suppose then it might pay to discuss this with the person who will be spraying the car when the time comes.

I neither need, nor want a high $ show car finish on this thing. But at the same time, I don't want it to peel off the first time I get a rock chip at the track.

I'm sure you have a compressor. I wouldn't waste my time and effort with anything that isn't catalyzed. If I were you, I'd buy a cheap spray gun. It opens all your options up. You can epoxy the bare metal, apply high build polyester, 2k primer, etc.. It is also much cheaper buying by the qt. or gallon than using rattle can. The rattle can will not be durable and I'll bet that the cost difference is in favor of buying a gun and mixing your own product.

Besides, any decent paint and body shop wouldn't paint over rattle can. That product was developed for small spot repairs, not large panels.
