I have been using Future for about 20 years and it is my "go to" for a gloss coat. I put it on using a medium flow setting on the airbrush and then quickly sweep the airbrush over the model at a distance of about 6 inches. Future is thin and will run, which is why you don't want the airbrush staying in one place for very long. When I have all of the panels covered, I let it sit for about 15 - 20 minutes and apply another coat. I will usually apply 4 - 5 coats. The thing that I like about using Future is that I can "read" the finish and adjust how I am applying it. If it is drying and the finish looks like real small pebbles, I am spraying too lightly or too far away. If it is drying in larger blobs, I am applying it too heavily. The good thing is that Future is self leveling to a degree and you can usually smooth out these problems with the additional coats.
