Thanks everyone for the encouragement, and Mike, I went back to check your build of the same kit. If it turns out near as well as your's did, I will be more than satisfied.
Here is my solution for the missing wing root detail. I had thought of using a strip of plastic sheet, but there isn't anything thin enough for the scale. I suppose I could of sanded beforehand, or even afterwards once glued to the fuselage, to arrive at a proper thickness. I know from working in the past with the Evergreen product, it tends to curl up when sliced really thin. Combined with liquid cement, I'm not sure if it would of been more mess than anything else.
1. Four layers of masking are taped together, and then cut into strips to make a masked trough for Tamiya's liquid surface primer.
2. Brushed on three layers, waiting about 2 mins each time as well as another short wait before removal of tape.
3. After drying overnight, a few passes with some fine sandpaper. A sewing needle is used to create holes for the final details.
I think the primar stage will really tell how successful this solution was. Also, once painted, the root areas is dark while fuselage is light grey - so that helps give the illusion of separated detail.
