I noticed the other day that the trapezoid fretboard inlays on my SSCM-1 (which was completed in 2021) had started lifting up. All of them from the 3rd to the 12th fret!
Has anyone else had this experience?
Reading online it looks like a relatively common issue!
Anyway, I followed the method suggested by the Stewmac video:

Add thin CA glue in the loose edges, cover with wax-paper, clamp using a capo.
Once dry, then use a razor blade as a scraper to tidy up the glue marks and get a flat surface.
Re-oil the board.
I think it was very successful!
