Soffits and fascias

[borzio]

Hi Guys, advice needed again:
I'm going to be removing the gutters on the bungalow this year and before putting new stuff up I'm looking to paint the fascias and soffits.
Both of these are in excellent condition for a 1930s house and are pine about 3/4 inch thick, one black gloss and the other white gloss. (painted before I bought the house).

What's the best exterior gloss/eggshell, (and which is the better option), and should the rubbed down paint be primed? I want to cover the black with white to make it uniform, so anything special needed to stop the black showing through.
I used a dulux exterior 10 year paint on the garage a couple of years ago and the white didn't last going yellowish so I want to avoid same with the house.
Your help's appreciated as always

Two coats of Dulux Trade Weathershield (oil based) undercoat and one coat of their DTW oil based gloss should be sufficient.

You can spot prime with either their blue liquid primer or any waterbased primer/UC.

Dulux Trade ≠ Dulux.

If it doesn't say Trade in the name, it is the rubbish retail stuff.

thanks opps, just the recommendation I was after.
The previous Dulux was watery sh*t to put on, and as stated didn't last anywhere near the 10 year ( not that I expected any claim like that to come true). Only reason I used it was I was given 2x 5tr tins that a family member had recently bought before deciding to move house to one which had upvc soffits and fascias. Swore I'd never buy their muck again. ( the diy version not trade!)
