One of my Cracked Pernbabuce builds is my personal guitar, an L00 inspired piece. The cracks lay open for years, but my recent post spurred me to try fixing it. I CA drop filled the cracks and put a couple of coats of varnish over it. I did not ry to make it perfect, because I doubt it will hold. But it has so far! There are 13 cracks, all in the most flat sawn section, mostly running as an 80 tree angle up from the lower right, both sides. I think this guitar is 90 percent of what it might have been, which is enough, actually.
