I just made a mistake yesterday. I was going to see how many coats of orange  acrylic it took if I put lots of thin coats on the little wheel. I was also playing around with the Olive Drab Faded which is Lacquer. I didn't get all the Olive washed out all the way and I accidentally started using the Paint brush I had been painting Olive Drab to paint orange. Could that cause a problem adding orange to the wheel later?
