Post sanding paint question

[Namco]

I'm at the sanding/paint phase of my cabinet work. I've sanded the cab with medium grit sandpaper and intend on painting over the existing roughed/smothed paint with a fresh coat of black semi-gloss latex on a foam roller. The question I have is about the amount of dust on the cabinet after sanding. It's coated with a fine black layer of dust. Do I wipe that stuff off with damp rags or just paint over it?

this may seem like a silly reply, but you've already invested the time and energy why not take 3-5 minutes and wipe it clean.  I've always made sure whatever surface I'm painting is clean and I've never had any issues.

Yeah, I would go to Home Depot or Lowes and get some tack cloth.  It would take less time to wipe it than you took sanding it.

Yeah totally right, I didn't know if it mattered or not, but obviously I shouldn't be lazy and should just give 'er a wipedown. lol

Shouldn't you also primer it first with Kilz or something so those swirls you worked into the finish with the sandpaper don't show through the new paint?

good primer always makes a big difference
