When we rebuild machines, we started by taking a paint sample to a local commercial paint store and had them match it in an enamel. We use this to repaint machines and it seems to hold up pretty well. I suggest you do the same as I don't believe Fadal has the blue paint. I believe they sell the off white or "Gray" paint but there is nothing special about it.
Save yourself some money and just take some samples in and let your local paint expert mix it for you.
If you want the labels or stickers for the machine, FadalCNC.com has them in stock.
Good luck and have a nice holiday.
