When building an LED array do you need to sand, buff or otherwise prepare the surface of the heatsink? I recall reading about people doing this, but can"t seem to find the info. anywhere. I'm planning to use thermal pads to mount the LEDs... if that makes a difference.

My guess would be just making sure the surface is clean of any residue left from production.
well if you are using any type of thermal paste you need to clean it of residue, I recommend rubbing alcohol it is cheap and very effective as it dries fast and doesn't leave any residue behind.
