Aerosols dry but they don't ever cure. There is no catalyst or activator in them for that to happen unless you're talking about a 2k packed spray bomb. With any regular spray bomb paint when putting something over it the solvents can bite back into the previous paint and turn it into wrinkle finish even if you do it a year later. With the colors dry and no scuffing there's no way to tell if the adhesion is going to be good or not. Shoot a test panel and make sure it works. You never can tell with spray bombs. A couple easy coats with lots of flash time before trying a wet coat on it. If it looks good and you're happy I be tempted to leave it as is.

This is correct and good advice, although the statement that aerosol paints or any paint for that matter doesn't cure over time is incorrect. Aerosol paints do cure, or reach maximum hardness over time.

I understand what you are referring to, but paint curing is not exclusively defined by paints that undergo a chemical reaction, such as what happens when using a catalyst to alter the molecular structure of the paint. Drying over an extended period of time is a time tested way of curing paint and many other things.

Semantics aside, the term "cure", as used in my post, is an accurate use of the word and process.

Paint “DRY” happens when the solvents evaporate from your paint coating leaving the paint feeling dry to the touch even though it is not 100% dry.

Paint “CURE” happens when your paint coating has reached it’s maximum hardness and is completely 100% dry.
