I called Lowes who, even though it is discontinued with them, ordered me some directly from Rustoleum. The downside is I had to buy 6 cans. The upside is they were only 2.69 each. For those out there looking, may be worth it to give Lowes a call.
Anyone found anything close yet? I tried hunter green with a matte spray, but it just isn't the same. I've really enjoyed using the spray cans because I don't use an airbrush and I don't think I would enjoy brushing on a custom-mixed color.
If anyone has a suggestion I'm all ears.
