The recreation of Kevin Flynn's right gauntlet was daunting. I wasn't pleased with my first two attempts, but the third attempt worked well. For reference, here are some images and screenshots of the gauntlet that Jeff Bridges wore. These are what I based my work on:
For my recreation, I used the same craft foam I used for the helmet neck visor. For the line art, I used ink jet matte white vinyl adhesive sheets for the 3 circuit patterns on the hand, elbow, and central panel. For the 3 long lines, I masked and airbrushed them. I used GIMP to digitize the original graphics by placing them as background layers and retracing and interpolating them into new layers. So my graphics are very true to the original work.
The foam is hard to paint, requiring about 3 coats of primer and 3 coats of flat white enamel, sanded in between. In printing the circuit patterns, I noticed that the matte white vinyl ink jet sheets were a brighter white than the surrounding enamel, so I spent a lot of trial and error to color match and reprint with a matching off-white background.
I am very pleased with the final result. The printed vinyl graphics adhere well and, after solving the color matching of the background, blend into the prop very well. Getting the central panel inset adhered was tedious; I used drops of superglue in small segments and worked my way around the boundary, holding each segment for 60 seconds or so before moving on to the next. After about half an hour, I had the inset fastened in completely. Here are some pictures:
