Not that I know of. If you'll find a way to buy it in larger quantities, let me know. :) I'm currently using Vallejo acrylic paint in bottles with droppers, so I can reliably drop predetermined number of drops without throwing anything away. Also, i've become an expert in deciding, how much paint I'll need for the job; rarely I throw away more than a couple of drops. :)
At least I can airbrush as much finish as I want, since I've bought 2 bottles of future... :)
