Latex, the real Latex, never gets completely hard, it's basically a rubber coating. However, since there is a proliferation of the “art” of misusing seemingly specific words to describe coatings today, the stuff in the can could be anything.

Here's what I'd do.... spray a non porous surface, Melamine is what I use, But a piece of galvanized metal, or glass, anything the paint will not soak into, with the H2O. Wait a few days, as you would any experimental finish. Mask off a section to keep it un-coated, then spray with the Nitro.... If it looks like a topo map the next day, wait another week, then try again on the masked off section. If it still crinkles, fuggidaboutit.... it's not compatible.

Oh, put down good thick wet coats, really make the chemistry “dance” to see if they can get along with each other.
