DIY refillable spray can

For this idea, you will need a nipple with a nipple from the car drive, a plastic bottle, a spray bottle spray gun. It is important to remove the spray button from the can along with the tube, the length of which should almost touch the bottom of the bottle so that the paint is used to the maximum.

The hole for the automobile nipple should be slightly smaller than its landing diameter, otherwise it will let air through. It is important not to pump the homemade bottle with air, the connections may not withstand strong pressure, but it is definitely enough to spray paint.
