Mysterious Blue Spots Appearing on Painted Plywood

I have had several customers in the New England region recently report blue spots appearing on white painted plywood over the past few months, several months after their cabinets were installed. Has anyone one else seen this sort of spotting or know what causes it?

I would suggest you contact your finish manufacturer. They generally have decent support teams to hopefully shed some light on that very unusual problem. I've never seen anything quite like it.
You painted it? ... or did it come prepainted? Something in the wood, bleed through from the glue or factory contamination. Something beyond your control but from the customer's point of view this is on you! A pigmented white shellac might stop the bleed and a heavy duty #8 primer over that.
