Tried a new spray-on curing compound on a garage slab in July

It was 95 degrees and the stuff set up so fast it left these weird, streaky patches. I had to go back with a broom finish to even it out. Anyone know a better product for hot weather pours?

That "set up so fast" thing is the whole point in the heat. You want it to cure fast to lock the water in. The streaks just mean you sprayed it unevenly. Next time, use a garden sprayer with a fan tip and keep the nozzle the same distance from the slab the whole time. A broom finish after defeats the purpose of the membrane.

But a broom finish doesn't ruin the membrane if you're just knocking down the high spots. Seen it hold up fine.

Yeah @emery_lopez, I used to think that too until I saw one fail.
