Regardless of what paint you use, always, ALWAYS, prep.
Make any necessary repairs and strip off any old finish if needed (I stripped the top of this piece, then sanded it down starting with 120 grit sandpaper, then 180 grit, then 220 grit and stained it using mahogany gel stain).
Clean the piece really well. I prefer Frenchic's Sugar Soap. It removes grease and oils, dirt and grime, even nicotine! But it isn't harsh like other cleaners. Totally Awesome from the dollar store and krud kutter are also great cleaners. Scuff sand using 220 grit sandpaper. Then wipe down with water to remove any residue and dust.
