I’ve never seen such a mess in my life. I’m in the middle of an extensive automotive rebuild project, and there’s been so much paint spraying it feels like we’re going through gallons every day! There are some big parts that get sprayed with enamel out of a gun but all the small bits and pieces need to be coated with Rustoleum gloss blackout- which is only available as cans (sadly). The primer has no problems at all; however, for this black paint job on smaller items things have gotten pretty messy. We can’t go five minutes without one nozzle or another spitting watery black sludge everywhere: across shelves, onto walls – you name it! It gets worse when someone turns around while holding the spray gun, and suddenly you’ve got a nice big stripe of paint on your pants. Luckily for me, my wife doesn’t mind when I get home wearing only one pant leg and ask her to fix the mess at work!
We shake the cans plenty, so that shouldn’t be a problem. However, I don’t remember having as much trouble with Rustoleum paint we bought last year. Have you ever noticed quality issues lately with Rustoleum?
That’s not an uncommon problem with some cans of Rust-Oleum (for several reasons). First, if you shake the can for too long it can cause bubbles. Then, if you don’t have a good quality sprayer on your paint gun or don’t take enough time between parts to clean the nozzle then that can cause sputtering as well. Finally (and most commonly) Rust-Oleum makes their cans so cheap now that they are prone to leaking, which causes air in the inside of the can and allows liquid to pull back into the container after release instead of spraying out properly.
