The Tech Form looks fine...some folks use "coolant" as a generic word for whatever's in the cooling system.
Past Bash teching always included a prohibition against anti-freeze. The first year found folks buying distilled water off the shelves at the convenience store nearest the hotel at the last minute. I'm sure some folks slipped through with the greasy stuff...John and I teched everyone by ourselves. We found stuff like loose tools in the trunk, bungee-corded batteries, folks thinking gas pedal springs were "sorta like throttle return springs" and other assorted little things. But everyone stayed cool, nobody got irritated and everybody had fun.
Is there other stuff to be listed/checked? Hey, you're asking an SCCA Safety Steward (let my license lapse two years ago though), so having seen you describe yourself as "anal" I've got to tell you that you don't know what "anal" is.
But this is the Bash, so the whole concept is to have fun and be somewhat relaxed without undo pressure but to keep safety as the highest priority.
Folks go out in modern cars (Porsches, Vettes, Vipers, Miatas, etc.) on car club days and things are somewhat lax in terms of tech because they are modern cars with nothing leaking and things like anti-lock brakes and skid controls and modern tires to keep morons from killing themselves.
Cobras are the ultimate freedom...they will gladly allow you to kill yourself due to the lack of safety systems and a high HP-to-brain cell ratio. So,
antifreeze on the track with cars that love to swap ends just for sh!ts and giggles is even more of a concern...I've seen comparatively slow moving autocrossers spin like a one-winged fly from somebody's hose breaking.
You'll be fine...no reason for anyone to be black flagged due to a tech issue if the tech sheet is followed. Just dump the coolant.
