Acrylic primer undercoat will not last outside on fascia boards. As the Timber expands and contracts witht he weather the paint will not be able to cope with this and will start to flake off. Better to use an oil based paint. Dulux Gloss is fine but the weather shield gloss is much better.
I was going to use an oil based undercoat after waterbased primer, would that make any difference?
