If you still have some Akzo availible you can put it in a small airbrush for touch up, it worked well for me.
This works well, but if you by the cheapo airbrush from Harbor Freight buy the one with a glass jar. The plastic jar ones sort of melt when you clean them out in acetone...
You can also buy a badger 1 oz glass jar from your local hobby store for the HF one, they seem to fit.
