This is what you do when you think WD-40 sprays out too much.

Good common sense idea. After this video gets enough circulation, you'll be able to buy a bag of them on Amazon for $5 bucks.

How did those 1/4 turn paint nozzles work?
They went through a low to highest output range in their 1/4 turn.....and were made of good old plastic!

Thats a nice bit of work. if he could make and sell them for 10$ I'd buy one.
Although in the usual use case the big blast bottles are used and sprayed all over to protect the metal from rusting.
wd-40 is the least stinky and works.

Cool idea, but not too many can make it happen. A cheap and easy way lessen the flow: Heat the straw with a lighter while pulling lightly. Once it necks, hold steady until it freezes. Cut the middle of the neck. You know have a smaller low flow straw. This also works great for cleaning passages in carburators.
