sanding glossy surfaces for priming

[Evan Mann]

What's a good grit of sandpaper to use to sand glossy surfaces that need to be primed? Surfaces like cabinets or panel. Killz recommends to sand the surface and rough it up for maximum adhesion. I believe it works w/o sanding, but a few passes can't hurt. Is 100grit to coarse?

i'd use 150 or 220 and just give it a quick once over to knock the shine off. imho 100 is a bit too rough especially if its cheap sandpaper that has a few boulders in it.
