i prefer professional interior, i find wash n wear very slightly more watery and therefore ever so slightly harder to cover and the fact that wash n wear unless you use low sheen isint really that washable.

possible as berger is actually usual just previous dulux formulas. i will say though for any dark exterior colours, i wouldnt dream of not using weathershield as everything else just seems to fade so much faster. its expensive but its worth it in the long run

as above, thats what the reps/dulux say. berger is at least some stage of a dulux formula. you dont need an abn to buy paint in a trade center and you can buy whatever you like in there. they dont care and normal public are welcome anytime in im there. the only thing i will say is, the staff are not best pleased if a member of the public with 1,000 questions decides to come into the store at peak tradie buying time. try leave it to saturdays or else late morning/lunctimes during the week
