I have coated a number of models with future. It is a low risk operation. Which it why I like it. These are the two darkest that I have done. My layering process is rattle can enamel over bare styrene. No polishing or wet sanding. (Yes, I often have orange peel). I then apply Bare Metal Foil, then decals, then the bumpers. After the visuals are done, I brush apply future before the windows are installed. Apply it fast and heavy with a 3/8" wide brush. Avoid rebrushing areas that are starting to solidify or it will leave brush strokes. do not worry about any bubbles, they will go away on their own. You can apply it so heavy it runs off of the edges. Simply wick away the excess with paper towels. If you screw up a small area, let it cure overnight. You can wipe it off with tee shirt material soaked in household ammonia with out bothering the paint. Numerous times even. Try that with any other clear top coat. Also do not hold the body with your fingers. Mount it to something you can hold.
