It seems like it would be easy to mess up MDF by sanding it. The paper part, that is...

MDF is nothing but paper fibers so which part exactly are you talking about?
Sanding MDF is fine BTW and should be done before you apply the primer. I recomend a random orbital sander.
neuromancer:
I was thinking specifically of the paper laminate on the faces. It is very smooth as it is yet still has tooth, so why sand it? What grit do you use? I would understand sanding the edges if you had tool marks, but otherwise I don't see much point to that either.
I've read a variety of articles in magazines on painting MDF and I don't recall any of them mentioning sanding, but maybe I just didn't read close enough.

the paint will stick better if you sand it, don't use anything rough on it. a light grit will work fine.

I got to thinking about this a little more when I looked at the sheetrock in my house and realized that the paper coating on it is essentially the same as the paper coating on MDF.

I don't think MDF has a paper covering like drywall, it's basicly very fine saw dust that is pressed together under huge pressure, which is why it has that weight to it.
