Second guessing methanol

[A440A@AOL.COM]

Greetings all, 
    I was asked to deal with a chronic problem on a 1998 Steinway L.  
"Sticking keys". 
    The cause was excessively tight hammer flange centers.  Being a 
warranty-eligible problem, I wanted to stay within their recommendation, so I 
called and was told to put one drop of methanol on each center and leave 
totally untouched for 24 hours.   I did, and the hammers are once again 
swinging as they should.  
    Now,  I KNOW that if I had repinned this hammerline, I would have had no 
further problems, (at least so far imhe).  However,  the ease of the liquid 
diet has a lot going for it, and if the result is equally durable, it is a 
no-brainer.  There were two prior visits by the dealer's techs, so it is 
possible that the methanol was already tried, and if so, I will be repinning 
this thing later.  
    Who on the list has experience of using this straight methanol on the new 
Steinway's pinning?
Thanks,

poison!)
