It's generally just some sort of liquid glue that hardens over time into something very 
brittle.  You should be able to just carefully chip it away with a small Xacto or even jeweler 
screwdriver, just be careful.  There's really no need to replace the glue, it just holds 
components to the board before flow soldering during mechanized assembly.  You'll be 
doing your replacement by hand, so you just stick the leads through the holes and spread 
them a bit to hold them for soldering.

I'm really impressed that you are component-level rebuilding your DW8K power supply, 
but if it starts getting too expensive, pick up a "parts" DW8K, something with physically 
damaged keys or cracked case or something, and scavenge the power supply.

well, the really impressive thing is how people are so willing to help out and share their knowledge. all i'm really doing is following instructions. however, i had been feeling kind of impressed with myself - up until a couple hours ago. i was desoldering one of the voltage converters and i ended up lifting the copper pads, all three of them. shit! i'm using a push-pump desolderer and it is just not doing it for me. someone recommended desoldering braid. is there a specific kind that works well?
i've tried some stuff from radio shack and i thought it sucked.
is there a cure for what i've done? or is it time to start looking for another pwr supply board?
