I’ve had a different experience with using future. I shoot from an airbrush at 10-15 PSI and at about 1 inch from the model. One of the best modelers (in my opinion) on this forum (Pixilator) suggested this technique to me. Spray as if you’re a scale painter. Makes sense to me. Anyway, I’ve had success using this method. Thanks Pix.
The reason I do this is becuase if you have low humidity, and spray at high pressure and/or far away from the model, you may find that you get a grainy, or pebbly finish because the future may dry up before it gets to the surface of the model. If it dries up too much, it will lose its ability to flow together properly. (This is what happened to me, a few weeks ago.)

I use decal setting solutions to help hide the decal film, allowing it to blend into the finish. I also use decal solvents to help get the decal to conform to panel lines or other surface details. Be careful when using these things, as they actually dissolve the decal.
That’s how they work, so practice before you start.
Speaking of practice, that’s the best advice I can give you. I’ve screwed up several times, trying out new techniques.
I’ve learned that there are many “unspoken” variables that come into play when trying out new techniques. So, before you put it on the line with a 3/4 finished model, save yourself some grief and try it out on an old “hulk” model or get a sheet of styrene from a hobby shop. Take the extra two or three days to practice future application (for instance).
It seems like a lot but I blew a whole week of painting effort with my first botched Future application! It will save you headaches, and you’ll get the kinks worked out before. In the end, your model will thank you.
