Karen, Glyptal is an electrical insulator, but not a heat insulator. I have
a probe in my Ragusa pan, and the transmission fluid never exceeds 160
degrees in the pan. So, i would say that your concerns about it insulating
the fluid from the cooling fins are of little consequence.

Thanks Jim. I was concerned about the glyptal being able to handle the heat of our application,
so your observation is helpful. I recall Manny saying something about seeing 300F temps in there
at one point, though I can't remember where in the system. That made me concerned the glyptal might not hold up to a
heavy vehicle going up and down big hills with a towd... I think there are alternative products that can
handle the heat and the ATF, but I haven't found a definitive enough version yet. "Silver Seal Fluid Weld"
can supposedly do the job, but it appears to be a thick paste, is just as expensive as glyptal, but
can be bought in smaller quantities.

It appears virtually all modern aluminum cast automotive parts are pre-sealed by various industrial processes,
but those don't typically lend themselves to DIY work. I've also read that in the past, GM, etc, used epoxy paste
or RTF for leaky castings. A paint would be a lot easier. I'll be very interested to hear how Ken's experiment turns out.

thanks,
Karen
