You'll get more different answers than there are products available. With that, anything solvent based will shrink. Period. How much is dependent on the solvents and base materials, and how long you let it cure. If you can let it set, you can sand out any shrinkage with time. 2 products I've used with great success: Clausen All-U-Need: http://www.smartshoppersinc.com/AutomotiveFinishes/Clausen_Primer.htmlTamco: http://www.tamcopaint.com/hpdtmgr2kprw.htmlThey are 2 completely different products, both have had great results. And I NEVER use one system beginning to end, so let the nay-saying begin.

EVERY primer will shrink. Which is why most high end restoration shops will let a vehicle sit in the final coat of primer for at least 30 days before they do the final sand and paint. This allows all of the shrinking to take place before final sanding.

That is exactly right! It's all about the prep, and that means what is under the primer. Personally, I use all PPG products with very good results. No, it is not cheap. But it hasn't failed me in the past twenty years, either. If you had asked about the cheapest primer on the market, I would probably say use the brand most have suggested here. But you didn't.

I use dupont nason 2k, since I use dupont products 95% of the time.
I use spi epoxy, not as a building primer, but to seal freshly stripped/blasted metal.

Since I dry sand every step down to the final wet sand of 600 I have found Martin Senours Tech Prime hard to beat. As mentioned before I also leave the last coat before final sand sit for as long as is possible to let any uglies creep back before color is applied.

This is correct BUT not all primers shrink. SPI epoxy primer does not shrink. Typical 2K primers will shrink.
