New Spray Paint Cans That Stop Spraying After The First Squirt?

-
To the best of my knowledge, the spray any position models do not clear themselves flipping them over, so yes, it can be a problem.
Nope, they can't - cause any angle includes flipped over. LOL
 
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.
 
I have noticed that the newer, large, white nozzles plug more frequently that the old style too. I also keep a baby food jar with some laquer thinner in it for soaking the pugged nozzles and change out a plugged one for a soaked one, which usually works.
 
Sometimes they are just bad, others... well, i was taught to shake the cans 1st... a lot...then when I was done with the can, I was to turn it upside down and hit the button to clear the paint from the tip....so that it would work next time , aka not be clogged.
 
I switched nozzles (like I mentioned in my first post) and it did not solve the problem. Sometimes it is the nozzle, but in my case, something else was going on in the guts of the can.

Not sure what they do internally to allow it to spray any direction. Older cans that have a pickup tube to the bottom would do that. If they sat a long time it's got the heavy goo in the bottom till you shake it. One push of the button and it sucked it into the tube and clogged. That tube to the bottom is what allowed you to clear the nozzle cause it only blew out propellant when inverted.
 
I like tossing the cans into the burn barrel, sort makes boom like the guys that ignite black powder under 200 lb anvils!

in 6th grade there was a kid that did that. He was in the hospital for several days with massive facial lacerations. As soon as he tossed it into the burn barrel it exploded and shot metal pieces at him. I remember him telling me about it. I used to throw them in the burn barrel too... but not since then.
 
I have cleaned nozzles with aerosol carb cleaner followed by compressed air. Have also pressurized cans that had lost pressure. Be sure you have regulated pressure to not burst the can.

Bad Idea throwing any aerosal cans in a fire... They're not meant to burn, they explode.
While in the Navy in 64, one of our paint lockers caught on fire. Me and another guy tried getting it under control till the base fire dept could get there, didn't work, aerosal cans were going off like bombs, and blowing paint all over the place. The regular gallon cans of lacquer (for aircraft) were going off also. We were using those big fire bottles on wheels, and they were not enough. What a mess.
I never could proove it but I always thought one of those guys that got drafted, that we received, in our outfit, (yes the Navy got a few draftees, at the big build up for Viet Nam) threw a cig in there. Long time ago now.

Propane is used as the propellant in them. In cooler weather the propane contract, it loses pressure. Just like your propane grill won't work as well in cooler weather. It is possible for contaminants to get inside, but not likely. I mean it is possible to get a bad can once in a while; no QC is perfect. But it does have a temperature range.

When the can I mentioned in post #1 locked up, it was putting out nothing--no way to have cleared it spraying upside down or not, it just quit completed like someone had turned the water faucet off tightly. And why it started working again after having been in the sun is still a mystery, I wonder sometimes what is going on inside those cans (and closed bedroom doors, for that matter).
Primers have a huge amount of pigment in them. If not at right temp or shook very well the material might be clumped up. Same thing happens to me sometimes.
 
I used to use Rustoleum mostly. But lately Duplicolor seems to spray better. More uniform and less plugging.
 
Krylon has a GREAT spray tip.

Patented, IIRC.

Almost never clogs and has a really good fan pattern.

Krylon has come a long way in the past decade or so.

Strongly agree - great paint, nice finish. Used a bunch of theirs on my car. Mostly 'Dual', and 'Maxx'
I think both of those will work on just about anything metal, plastic.
I don't think they do 'any angle' As I recall can still flip it and clear.
 
...and the Krylon "Tough Rust" semi-flat is an almost perfect match for Mopar accessory black.

The only downside is that the cans themselves are not labeled, so if you loose the cap or have 2 caps off different paints (esp flat and semi-flat black), good luck matching them up or grabbing the right one.

Take a sharpie and write the color/number on the bottom.
 
That's exactly what I do but should I have to?
