[pianotech] Spit foam on Tuning Pins

[Randy]

Did you apply Catalyst after the superglue?  That can cause foaming.

However, spit-like foam surrounded the tuning pins, in some cases well past the coils and toward the top of the pins. In addition, the nickel plated pins turned a rust color. I've done many CA glue jobs to tuning pins and have had minor foaming but never anything like this nor any pin discoloration. Could some solution have been on the pins/pinblock before the application? Any ideas or similar experiences? Thanks.
