I'll add one more thing also. I really like Minnflier's recomendation. Iwould tack glue a strip flull length of the surface about 1/2" behind the Leading edge prior to makeing the cuts.That will keep from squeezing or spreading the LE when the replacements are put in place. You could also do a serious pin job on a building board, leaving the width of the LE hanging over the edge. You don't wan't to build a twist into it with the repairs. Once the LErepairs are made, then remove the strip.
