Note that the guitar forums that popped up with a Google search on LMI said that it has a relatively short shelf life and some handling/use requirements. And, as always, different users had different experiences. So, if you order some, do your Google search.
For now, I'll just stick with Gorrilla white glue, cut with water.
I did a little test comparing PICA, Elmers (yellow), and Gorrilla white. I edge-joined pieces of 1/16th and then glued them to a convex frame. I then sanded the curved surface as carefully as I could to see which would make the smoothest joint. I then gave it a blind "touch test". I also took the frame to an NVCL meeting so everyone could check it out personally.
Results? PICA came in first (almost imperceptible joint line feel), Gorrilla came in second (almost a tie with PICA), but Elmers was a very clear third with a bump or pucker at the seam line.
