I hooked up the nozzle from this to a can of tremclad rust paint to give it a test in the longitudinals. Much like they show on the website, it does a pretty good job misting out the end of the hose. After a couple seconds tho, the paint will come pouring out of seams, openings...etc. so you WILL make a mess if you use this.

It sounds like you need like 4-5 cans to do most cars, at $20+ each tho. Buy one, clean up the nozzle and reuse in cheaper rust paint cans.
