We have no idea where you live and what your retail stores look like. Asking us where we can find it won't help you at all. I can find it easily at the B&M home improvement stores around me, where they stock all kinds of spray paint. Everyone has said so far that they find at at HD. But you obviously couldn't.
Maybe spray paint is banned in Allbums, Nowhere?
Asking for automotive spray paint is your best bet. Or look online. (But spray paint has a bunch of shipping regulations).

"In short, the same knowledge that underlies the ability to produce correct judgement is also the knowledge that underlies the ability to recognize correct judgement. To lack the former is to be deficient in the latter."
Kruger and Dunning (1999)
