I went ahead and painted it! I probably painted too much of the top / close to the rim, but I also installed a spout on the bottom so I'm not too worried about run over except for during clean up... I'm brewing tomorrow and / or Sunday, I'll be sure to post pictures and my after thoughts then!
This may seem like a silly idea, but do you think there is any insulating value to such an intense paint? (I used the Rustoleum 2000 degree paint mentioned above.)
