I remember in the "olden days " , I could get a green and clear " Aircraft epoxy" from LMI...When I called them and asked them about it, they said it was overkill, and no longer carried it....This stuff was reportadly...." Used in place of welds on aircraft"...I used it for 3 years and it dissappeared...What is it???...P.S. Many punk guitars still together with same headstock!
