I taped off some stripes. I did not measure anything. I simply started at one corner and worked my way to the other corner and taped around the edge to create a border.
This is a metallic gray acrylic paint.
I lightly sanded the gray metallic stripes and I went over the teal stripes with a foam brush that had just a tiny about of white paint on it. If you look closely you can see a tiny bit of yellow I missed on the second time around. It didn't bother me so I left it.
