Sealer and Primer?

Iíve completed building my first ever set of kitchen cabinet doors and drawer fronts. The rails and styles were made from Poplar and the panels are MDF (already sealed). Now, Iím prepping for paint.

Would it be best to use a sanding sealer in combination with a primer, BIN or otherwise? Or can I skip the sealer?

I did ďsealĒ the end grain of the styles with glue/saw dust.

Sanding sealer is for polyurethane and varnish. You want a sandable primer, like Sherwin Williams wall & wood primer. Prime then lightly sand with 180 grit.

Way back when I was an apprentice I worked for a guy who would mix sanding sealer with oil base enamel undercoater and use it for his first coat of primer over raw interior wood, straight undercoater for the 2nd coat and then oil base enamel for the top coat. It's been 50 yrs since I've heard of anyone doing that.

On your doors I'd apply 1 coat of an oil base primer, followed by 2 coats of latex enamel. Sand lightly and remove the dust between coats.
