As I mentioned the gentleman was supportive and authorized the aforementioned warranty service, but I think I might have to ream and repin at least a portion of these. Opinions? This gets back to the basic difference between the two ideas which are not, in themselves, incompatible.  The alcohol/water treatment causes the wood to swell, temporarily, thus physically *compressing* the bushing cloth.  When it dries, the joint is bound to be looser because of the compression. The Protek, while an excellent product and remedy in many cases, would only make the tight joint more slippery in this case.  While that may work in the short term, it could well be that once the lube has dried up, the joint will be too tight again.  In the case where any oxidation at all may be the cause of the problem, the Protek will help and be long term unless it is a very severe case of an old and little used piano. I have experienced first hand and others have noted that alcohol/water treatments can actually cause the joint to become too lose and need repinning with a *larger* sized pin. I guess the assumption here is that no one, not even Steinway would be willing to pay for someone to actually take each flange off, depin and carefully ream and burnish it?  That's what a factory or Concert & Artist technician would do, I would think. I think the response to your last comment about having to ream and repin at least a portion is "yes", regardless of which method you choose.
