I did some Layout work and put the panel lines on the fuse with some 1/32 Chart tape I got from Amazon. I'll put about 6 or 7 layers of primer just on the tape. then you wet sand the tape till you sand all the primer off of it. you can then pull the tape off and it will leave a depression and show a line. You can very lightly sand the lines to get rid of the ridges. If you get to aggressive with sanding the line will disappear.
