If it matters to anyone, Rustoleum's Industrial product doesn't come in rattle cans. It's only in bulk containers, and it has a specific primer that goes with that line. It can be sprayed, but in a traditional spray gun with enough orifice to flow the paint. I used it on about 200' of custom deck railing, and after five years it looks like the day it was sprayed. Rattle cans are for hobbys.
