Aluminium primer is great for knotty, resinous timber, but you shouldn't use the Dulux quick drying acrylic weathershield undercoat over an aluminium primer, it must be an oil based undercoat over aluminium.
Thanks,yeah I'm gonna use the oil based u/c and gloss so their wont be any probs using this primer with it?
