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.
