Paint flaking off bench

[H F]

A few months ago we sanded our garden bench and applied two coats of Cuprinol garden furniture paint.

 

A few weeks ago, the paint started flaking in some areas, and just on the main seating area. Nowhere else. I've just sanded it down, to treat and reapply the paint and have found, what I think is the culprit: little white areas in the wood, and these are the areas where the flaking started.

 

I don't want to repaint this, if it's just going to flake again.

 

Any suggestions how I treat this?

They look like some kind of filler but normally paint sticks well to filler. I wonder if its expanding and contracting at different rates in the sun? Was it cracking around the edges of the white spots?

 

Wait for other suggestions but perhaps drill out the filler and glue in wood dowels?

Tempted to say clear something so you can monitor.

 

Do Osmo do one?

We have wood treatments, I just wasn't sure whether we just go straight over these 'dots'. I think we'll treat it and paint it, and see what happens.
