So, I've been doing the toothpick thing. I tried shaping a toothpick to a sort of "chisel tip", and touching the nibs at an angle. I had better control after sanding a toothpick square across, leaving a flat end about 1/32", and touching straight down onto the nibs. Because I'm working on clear parts, I had to put blue tape on the back side to help me see the rivets. I still had to move the parts around quite a bit because the rivets are really only visible when the light hits them at a certain angle. The hardest part has been getting just the right amount of paint on the toothpick. Thanks to all you kind gentlemen, I may get this task accomplished, at least to my satisfaction.
Here are some pics, what do you guys think?
