Pulled another from my other tire leaving a rest stop and went straight back to that mechanic for the same. Don't know if I needed it but had no more issues the rest of the week (in true goat head territory the whole time).
I've only ridden that bike a couple of times since then and not for the past month. Saw this and went straight for the bike. Tires still had enough air to keep the rims off the pavement but that was it. Pumped to 100 psi, drained the valves at 6:00 and left the bike hanging with them at high noon. Thanks.
A new habit to learn! (And another reason not to add sealant until the first flat happens if that bike isn't a regular rider. I have 6 and ride what I feel like. Sometimes bikes get parked for many months.)
Edit: I still don't know what my Corsa G+ tubes are. I think latex but perhaps thicker latex. I seem to recall my silks of a former millennium going flatter sooner, These tires are rideable the next day, just soft. (28c and I'm light.) The ride is pretty sublime and hints latex.
I agree that sealant works well for goatheads, not sure why someone would think otherwise.
I'd bet a nickel that the Vittoria Corsa sew-ups have the same thicker (pink!) latex tubes that Vittoria sells separately, that I use on my clinchers. They do hold air longer than the old thinner natural latex ones did in Clement Criterium Setas. I may try riding my new Corsa Control Graphene 2.0 sew-ups without sealant at first, and carry a bottle of Stan's with me (no syringe needed if you're careful), but I'd expect my first flat in the field to change my mind back if I do...
Both of mine that use sealant are ridden regularly, and I'm in true goathead land.
