	Typically the ultrathin CA wicks right into the wood pretty much  
instantaneously. Unless you are pouring it on, there's no need for  
protective cover. I apply it as I tune (when I come upon the  
offending pin), and go back to that pin to re-tune when I am done. It  
cures pretty fast unless it is dead dry of winter, below 15% RH. I  
blow on it when it's real dry, and that seems enough to do the trick  
most of the time. Accelerator can discolor the plate paint - as can  
stray CA on some finishes, so use care with the tip, getting it over  
the hole before any CA runs out, especially on your fussy customer  
instruments. I first found this out on a 5 year old Steinway B.  
Turned the paint green. (This was doping a couple of the lowest 5 or  
so pins, which tend to be loose).
