Has anyone done the SPRAY PAINT + MUD technique 🤔

Submitted to Community Café

Again and again I have seen and received subscription emails with bloggers using a spray paint— mud technique for unique finish. It seems to be used commonly on solid hard surfaces like pottery and vases. Today’s email was showing it on pumpkins.
Has anyone tried this?
It seems to go against everything you want to accomplish with a spray painted finish.

Again today I got another subscription email describing it.

Wonder how it looks in person?
Is it more unique than using a paint product? Im guessing mud has a chalky patina.
