half empty spray cans

Right now I have 3 or 4 half empty spray cans on my workbench that won't spray. Shake them and there is plenty of oil, wd 40, pb blaster, rust eater,etc. Just out of air. I'm not talking about paint. Do you cut them open to use the rest of the container or use them for 22 targets? Ellis
 
Just use a screw driver to punch a hole in them near the bottom. Then they are dribble cans rather than spray cans.

A .22lr doesn't have enough energy for them to be good targets.
 
Target practice. My son and I shoot 22 lr at frozen water bottles and spray paint cans at 60 plus yards. Paint cans are better. Mom does not like it because her trees get paint all over them.
 

I pull the spray nozzle off and give them a shot of compressed air. Then replace the nozzle and many times they will spray for a while again.

It works best when the spray nozzle is female and you can get on the male part of the valve extending out of the can. Depress this to open the valve and hit it with the air. You will get the hang of it after a while.

I can't say I have ever tried it when the spray nozzle is male. I expect one would need to come up with something on the end of the compressor blow gun to reach inside to open the valve.

Best if you don't try this inside. It is kind of like playing with skunks as a kid - you get sprayed once and a while.
 
If it's oil, I take the can opener on my gerber tool, and just put a small hole in the top of the van, near the outer edge. If it's paint, and it's not the nozzle clogged, I throw it into the shop woodstove. Makes a little whump, and the lid of the stove lifts a little.
 
Most people don't know there are two kinds of spray cans...those you shake and those you don't. Unless it says shake on it..don'tshake it. Those kind have the propelant sitting on the bottom and if you shake it the propelant goes out with the product, leaving stuff in the can and nothing to push it out. My pet peeve,lol.
 
I have an older budddy that told me to take the can and fold it in 1/2 and it will build up a little presure to get a little more out of the can. I tryed it and it works. wd-40 , paint
 
That's why God made the Colt 45 Auto. I bought my first "bring back" from a Vet in 1967 for $25.
 
I have a Beeman pellet rifle that shoots at 1100 fps. My grandson (age 11) was at the house for the weekend and we decided to shoot "stuff". In the pile of cans was one of the marker cans of orange paint. The nozzle was messed up and wouldn't work right, but the can was full. I set it up with the rest and made sure he was the one that got that shot. Should have seen the look on his face when that one launched and sprayed orange paint like a whirlygig.
 
A 22lr has plenty of power, a 22 short will tear a can up good as well. To get rid of several hunderd spray cans last fall I shot with both till ran out of shorts. Lnined them up so one shot would do 5 cans at a time and they would be stuck together. Scrap yard to take they had to be puntured. What I use to paint a lot of machinery with.
 
Most of the time the propellant isn't gone. It's the nozzle stopped up. The easiest fix is to take the nozzle off a good can to use on it or you can soak the nozzle in lacquer thinner to clean it out.
 
Use to buy stuff in case volume but have stopped that for this reason.I still have good luck just putting the can in the sunlight and it will come back to life.The suns heat does its thing and you can get the rest of your purchase out or at least some more
 
I heard of a woman that was burning her garbage that had an empty aerosol can of hair spray in the garbage. She was killed when the can exploded.
 
I sent a letter to customer service at Rust-Oleum
2 years ago about a case of spray cans,(12) where
all of the nozzles got plugged/stuck. They sent me a little package with 100 free spray can nozzles. AND, it worked! the original nozzles
may have been defective--or, After that, I shook
the cans longer.
