    I received a call from someone with a ~15 y/o grand with the fronts of the keytops lifting. What would be the best glue to tack these back down? Roo Glue? CA? They are not curling, just being able to lift the front on the keytop.

    I had a similar experience. I used PVC-E glue. It worked well. I have a friend who swears by Roo-glue, so that's a good option as well. Make sure to clamp it well while drying.

    I would avoid using CA glue because it can get messy and it can ooze/flow out. Better to use Roo Glue or PVC-E and apply it by putting some on an index card and swiping it under the keytop which will spread it evenly. Slightly pry the keytop up, swipe the glue and press the keytop down. I have used painters tape as a clamp to hold the keytop to the keystick without a problem however a long clamp can me made with a piece of wood that spans several keys and a squeeze type woodworking clamp can be used at each end.

    You know, If most of them are loose, and some are falling off, I would call Yamaha support. They might make a warranty exception.

    I have 11 C2 Disklaviers dating from 2012. Four of them, so far, have started losing their keytops. Roo Glue has worked well, pressing them firmly but not clamping.

    I’ve used both CA and PVc-E, and both seem to work fine. The last one I did was using your favorite, Jon, Gluboost.

    Yamaha is generally still offering warranty work on those jobs, including keytop replacement. There’s quite a large number of pianos effected by their bad adhesion of the keytops.
