Years ago when CA was starting to be used on pins there were two extremes of application: one used 4 to 8 oz of glue, so much that glue ran everywhere. The other put barely any glue on at all. I find 1 to 2 oz is plenty for most pianos. Do a good soaking on the bushings as I believe that is where most of the holding power comes from. You likely have a piano that had barely any CA put on it, so a second application may be just the ticket. It is cheap and easy to try, so why not? You certainly won't make anything worse. If, after treating a few pins, it doesn't look like the CA is penetrating much, you might try drilling a tiny hole at the 6 o'clock position of the pin. Someone posted a protocol on this a few months ago for a second application scenario and said it worked well. You might check the archives, but as I recall you angle the drill so that it penetrates to the pinblock as it comes up to the pin. You are just creating another channel for the CA to travel further into the hole. Sounds like it should work great. The flipping the piano upside down and applying from the bottom will also work. Be sure to remove lid and hinges from rim before rolling it over. If it is only a few pins giving you grief, then remove the pin, squirt 6-8 drops of CA around the hole, re-insert pin. I have never had that not work.

A school that I tune for has a mid-1970s Kawai grand that's on its last legs. The tuning pins are too loose to hold a tuning, but somebody at some point in the past has already used CA glue on them. Is there any point in another CA application, or is it a hopeless case at this point?  I've already told them there's not a lot I can do for it at this point, but like schools everywhere there's not enough money to spend on extensive repairs or a new piano.
