I've rushed the process like that, and had problems.
One thing that might help you understand what you face is to think about why there's a curing time for the auto clear.
It's so the solvents that are in the clear can off gas, or evaporate, completely. They're important because they are the catalysts that allow the long chain molecules to form in the clear, giving it it's strength.
If you coat anything before it's cured, you run the risk of coating over solvent that's still off gassing. That's why there's a specific curing time. The only time that you can re coat before a product is fully cured is if the second coat is the same material, and the manuf. says so on the label.
Otherwise, you're asking for trouble.
I've gotten away with quick recoats of solvent based stuff when it's a spray glitter, or pastel fixative, and I've sped the process up with a hair dryer, but that's the only time I've had success.
The auto clear solvent may interfer with the Nu Lustre, or cause a poor bond. Because auto finishes have to be strong, it may have some pretty potent solvents in it.
It's safer to let it cure, scuff sand it, and then coat it. Remember, the clear epoxy will fill in the micro scratches, so the bait will still be clear.
And, if the epoxy does cure out, but doesn't bond, you'll ruin your lure getting the epoxy off so you can recoat it. That stuff, by design, is damn near bullet proof.
Been there, done that.
