Is it me and advancing age? Or did the paint can Mfrs. increase the pressure
required to operate the standard paint spray can nozzle? I seem to remember
that I could just about empty a can before my finger got a permanent dent.
Now I don't get 1/4 of the can before my forearm goes into seizure and my
finger is in pain.
I find that I cannot empty the can before the valve plugs up. Not the
nozzel but the valve in the can top Krylon seems to be the worst now.
Hate buying a can and throwing away more than half because I cannot
get anything out
Best thing I ever did for spraypainting was pick up a couple of the
trigger handles at various tag sales. I know Eastwood carries them,
but there's probably cheaper ones out there too...
Not recently, but have had the same problem with Rustoleum.
I figured they reformulated their mixture and/or didn't like
freezing temps in my garage. I try to keep everything
someplace where it doesn't freeze now. This was ~5 years
ago. Just been buy no-name cheap stuff ever since that
amazingly hasn't had that problem so far. But I don't use it
as much as I once did either...
Couple of things going on. CA's CARB caused a blanket reformulation
of paints in general and spray paints in particular in the late '80s-
early '90s. None to be had on the shelves shelves for almost a year
there. Supposed to reduce VOCs. The replacement stuff was thicker,
didn't spray as finely and ran if you looked cross-wise at it. Clogs
were more common than not.
Roll forward. They used to use propane for propellant on a lot of
paints, it was also a dandy solvent in liquid form, also a VOC.
Replaced with CO2. It dissolved in the fluid and you could get a full
can out before the foof went flat. Still had the same problems with
thick paint, clogs and runs.
Roll forward again. CO2 is now a nasty "greenhouse gas", probably
replaced with nitrogen, hard to get enough in the can to get complete
emptying. Haven't bought much spray paint since the second iteration,
I use thinned brush-type paint and a touchup gun. Best move I ever
made, getting that compressor. When I want a thin coat, I get a thin
coat. No clogs, no runs(that aren't my fault).
I won't buy paint in spray cans. Rust-O-Leum primer and enamels are good
examples of why -- the stuff in spray cans is a completely different
formulation, and nowhere near as good as the stuff they sell for brushing.
Except for some model paints, I haven't bought a spray can for 20 years.
I have a Badger "spray can," which is just a siphon-type mini spray gun, and
I use it for all the jobs for which I'd otherwise use a regular spray can. A
convenient way to supply air for ordinary jobs around the house is a spare
car tire and a Badger adapter for it. For heavier paints I heat the jar in
hot water until it will spray, or, as a last resort, I'll thin it. The
simple gun cleans up in about two minutes.
It also suits my personality: it's cheap as dirt. d8-)
Yep, and you really have to shake them now.
I had a bunch of Zinc Chromate replacement stuff that didn't
want to spreay well. Shook them on a real paint shaker for
a couple of minutes and they shaped right up.
Without the internal solvent (propane days) the solids seem
to clump up in the bottom. That clogs the tunes and the
can is useless.
Cheap cans are a lot worse too.
For what it's worth...
I have a small touch-up gun that works well and air-brush
setup, but... you have to get paint into the cup, thin
paint, hook to air compressor, take care of left over paint,
clean gun, put away all said above. I'm not that ambitious
I want to grab can off shelf, shake the daylights out of it
for several minutes, spray paint object, blow out/clear
nozzle, put away, wait for paint to dry. This used to be the
way it worked. Still have old ancient cans that work that
way. Pipe bumper on my truck still has black Rust-Oleum put
on this way 25 years ago...
Well, Rust-Oleum is far from cheap. I still have the problem
cans, way too much paint left in them to just toss. I'll
give your "super shake" plan a try next time I feel
ambitious. Got nothing to lose trying it :)
I have a touch-up gun, too, and a small portable compressor, but using the
Badger "spray can" is much quicker and easier. But it's not as simple as
shaking and spraying, it's true. I've just never found the Badger sprayer to
be enough trouble that it would make me go back to regular spray cans. When
I pump up a tire with my compressor, I usually can use it for several jobs
before filling it again.

I usually do the shaking in a stream of hot running water under the swing
faucet. The heat thins the paint, making it mix better and spray better.
The heat raises the pressure of the propellant, which is also good.
But don't do what my friend did. He put the spray can in a coffee can of
water, and heated it on the stove. While it was heating, he went outside,
"just for a minute," and got distracted talking to a neighbor. The pressure
built up in the spray can until the bottom blew out. It shot up like a
rocket, punched a hole in his ceiling, bulged the bottom of the coffee can,
broke the stove grate, and sprayed red paint all over his kitchen
Do the words "Do not puncture or incinerate can" mean nothing anymore?
About a year ago my curious mind became interested in learning the
outcome of the lawsuit by the woman's daughters. I couldn't find
anything definite, but a respondent on alt.legal checked it out through
his connections and said he couldn't find any evidence that it was
settled in favor of the plaintiffs.
That's their newer, fancier one. I've had mine for 30 years, and I have one
my uncle made 60 years ago. Simple siphon sprayers are a really easy job for
anyone with a lathe. All you need to machine are the siphon nozzle, the air
nozzle, and the air-hose fitting. The rest is a piece of plastic tube and a
glass jar with lid. An ordinary commercial coil spring is usually used to
hold the adjustment on the nozzle. The one my uncle made is maybe twice as
big as the Badger.
I've looked at that newer one you've linked to in a store, and it looks
good. I think that it's the same thing with a zippier design. Being one of
the original cheapskates, I don't think I'll buy one until my present one
wears out. I give it another 20 years.
Let us know how you like it if you do get one, Karl. And check with Badger
on their tire conversion gadget. I think I paid $3 or so for mine, 25 years
ago. It really is handy. (Oh, looking at that page, I think it's the same
thing as their Propel regulator. It screws into a can of Propel or an
ordinary Schrader valve stem. And it's included with the $18.99 kit! Good
