New Spray Paint Cans That Stop Spraying After The First Squirt?
This particular paint does have a problem with clogging.
I had several cans for my engine bay project and all eventually clogged, some very soon, like on the first use, as noted by the OP.
I kept a mason jar of reducer and dropped the spray heads in whenever they clogged, fishing out one that had been soaking, and blowing it out to use.
Poor design.
