I am just ordering my US kit. I do notice something on your LE sheeting that is different from what I do. A wise old builder told me not to glue the sheeting to the back edge of the leading edge stick. He says that you will always see that seam. We sand down the LE stick until it is flush with the ribs. Next youglue your sheeting on top of that strip. After it cures you wet the outside, fold it down and glue to ribs and spar. After both top and bottom sheets are down you sand your LE to shape with #80 and a long block. Now you don't see any seams.
