Right. I used a toothbrush and Acetone to remove the laquer.
However, my symptoms kind of match what I read on some other links: When you resolder only, chances are that the problem is also caused by old capacitors. The heat of the resoldering temporarily gives them a boost that then goes away. In my case the CC worked very well for a couple of weeks after I resoldered, and then started acting up again. Since it is a PIA to remove this thing, I am not putting it back in until I have put in new capacitors.
