and after around 3/4 hr I was ready for a quick sand and start to replace the leading edge. I cut back beyond the repair skin seams with the original wing skins by around 4" and added a complete new section of L/E. I also cross cut a small section where the new met the old and inserted a cross grain piece, this is so that when I carried out the final sand of the new L/E section it would sand back slower to avoid over sanding in to the original section and creating a dip, in practice I'm glad I did as the L/E of this wing is very soft!
