Clean the records before painting them. They should be clean, dry and dust-free to allow the paint to adhere properly.
Before using the marker for the first time, shake it for 60 seconds with the cap closed and gently press the tip onto a piece of paper several times to activate the ink flow. When the tip is full of ink, write on a piece of test paper with the marker.
Then use the YONO marker to draw wavy lines directly onto the record. Pump regularly to ensure an even application of paint. Allow the ink to dry well.
Trace the wavy line a little finer with a second color. Let everything dry well before the last step.
Finally, use a third color to add a very broad line to the two waves. Let everything dry well.
