I don't ever recall any discussion of this topic, although I may have just missed it. I am only a few weeks from painting and I got to wondering about where the factory-applied seam sealer was used on our cars originally. I will probably seal every possible seam, but does anyone have of any knowledge of this topic?

I believe that John has published quite a bit on seam sealer in past posts. To my knowledge, there was not much of any sealer used by the factory. As you say, I would seal every available seam, especially overlapped joints, with something such as 3M "Fast'n Firm". The excess can easily be wiped off to make a neat joint & it is paintable. Very good stuff. Maybe John will give more details & pics? Or his original references. Try a search for seam sealer on BCF - Austin-Healey.

I've been through several tubes of 3Ms Fast'n Firm seam sealer (also their not so fast version). For all the BMWs I work on, the best product I've found is the "brushable" seam sealer available from Eastwood (and I'm not that big of an Eastwood fan). I even like Eastwood's version better than 3Ms comparable brush on seam sealer. If pressed, I could probably come up with some detail pictures of the stuff...
