Theo, in the 70's I used Glyptal in a Z28 302 motor (DZ). It's purpose
was to confine any casting sand in the block from contaminating the oil.

Glyptal was originally a GE product, made in their chemicals division,
as mentioned on their website. Richard Feynman mentions the use of
Glyptal in one of his books, where I'm pretty sure he's talking about
the 40's. So it's not a recent thing. Glyptal's website has several
different products listed, and I'm sure that even historically GE made
different products for different applications. I was just curious about
the history of cross-pollination that put this electronics-industry
niche product in hot rodders' cars.
