I baked 20 and they look fine,a few "whiteish" spots before going in the oven, but none after baking. 5 passed wipe/smash . So because they did that, my money would be on them being OK with the second coat.
Just something I had never come across before.
Thanks Trev on the non-bake period too. That means I can stock pile and just have ONE bake session rather than multiple.
