Randy;<div>Thanks for your response. If you mean by catalyst, the accelerator, yes I do use it. I've had small amounts of the foam using it before, but never anything like this. (The next time I tune the instrument, I'll take a photo.) I've never had the pins turn a rust color either. I didn't treat the high treble, so the pins have no discoloration there. </div>
