Of course it can, young sir. Might make the Garfield the second choice, y'think? Of course, the stink doesn't compare, but time is an issue. If you've got the RH for CA to work, knock yourself out!

In my dry climate, it actually works better than CA glue. A 50-50 mix with methanol or denatured alcohol, applied with two or three passes, using a complete 4oz hypo bottle per block has been quite successful. The instrument needs to remain horizontal for at least 24 hours, and wait two weeks before tuning. Many of the pianos I doped over twenty years ago are still pretty snug. In most cases, only one or two pins may need to be sized-up. That's 99%.  A thinner solution can be used when there's not good penetration, and a super-thin solution can even-out the feel of jumpy blocks. I have never had a block destroyed by the solution, although we due loose track of customers, or they trade-up, or whatever. At the plant we've got about a cord of old blocks. I've seen many that had been doped, and if they are de-laminating, I'm sure they would have done it without the solution anyway. Penetration does seem to stay near the top, but hey..... that's where the pin is loose, no? <dd>   I believe that history and climate are very major factors, and that techs from different areas will have varied success. If I were to advise the world on the use of CA glue, based totally on how it works at 17% RH, I'd say don't bother. But.... I know how to deal with it, so I'd say knock yourself out.
