Well, after 5 hours at 280*F almost full of used ATF, the baked-on
Duplicolor 500*F Ceramic Engine Paint looks good. There is a very faint
difference in color where the ATF was vs exposed to air, but only barely
noticeable. I tried scratching the finish above and below that parting
line, using a nylon scraper. There was no effect on the paint in either
location. I'm sure I could easily penetrate the finish with a sharp metal
scribe, but see no reason to do so.

I'm going to install the Ragusa and run it. I certainly don't anticipate
any problems, but will report if I have any later.

Despite the apparent success of this method, I'd still recommend using
water glass, glyptal, or some other finish known to survive such
environments.
