White Exterior Filler?

[AndyDavis]

Can anyone recommend a strong and lasting exterior filler that leaves a white finish when dry. I was going to try the Exterior Polyfilla stuff but it goes grey when dry.

Is it going to be painted, If not it may not last outside open to the elements. Tetrion do a ready nixed filler that is very hard wearing, but as with most fillers they need painting over.

I'm repainting the outside of the house, it was painted ages ago and theres some cracks showing. After using the filler I'll be painting it over.

The Tetrion All Purpose Filler says to apply an oil based undercoat. I just want to apply the filler to the outside walls and then paint over with two coats of Dulux Weathershield paint. Is this going to work, or will the filler just fall off pretty quick. Is there something else I could use/do?
