I want to paint the fascia board on my garage. It is obviously many years
since it was painted white, long before my time, and there are rust-coloured
patches where there are nails. What should I do to stop this rust coming
through the new white gloss paint I intend to apply.

Any advice will be appreciated.

I have always found it much easier to replace with new, than to
prepare/repair for repainting, particularly in-place.

When you cut the new pieces, after temporarily fitting to check
for size, you can take them down and prepare/finish them in the
dry, refitting when finished.

Remember to let any new timber dry before choosing the pieces
to use. If you buy it from one of the sheds, you'll need to
buy about 3x what you need and choose the best 3rd a month
later. Another option is plastic facia of course.

It would be cheaper at that rate to buy western red cedar and enjoy
almost no wastage and a very long lived fascia (with or without paint).

What I did

Either replace the whole lot and use stainless or brass screws when
refixing or replace the rusty rubbish with stainless/brass.

I don't use anything but brass or stainless outside. Anything iron
based just doesn't last unless hot dip galvanised and even then there
is good HDG or bad...

Never tried it but how about knotting or stain block paint just on the
rust patches, then undercoat and finish coat as usual?

Rust doesn't normally bleed through oil based paint

Clean rust off .. could cover with a coat of knotting.
Then primer

+1 - but use an oil based primer than water based (and ditto for the other
coats).

Obvious I know, but some confuse the two and then wonder why, after applying
water based paints, the rust comes back - or the paint breaks down after a
short time.

As for myself, I only used oil based paints externally - even though it
takes longer to dry, it's far more durable and being tight-fisted, I like at
least a 5 year recoat life out of the stuff.
