Paint options for exterior woodwork

[GarF]

I've no hope of getting our regular painter this year, though given the extent/speed with which the paint is lifting on our bay windows I'm not sure I want him back anyway. So the time has come to do the first bit of outdoor painting I've tackled in ages, and I have to confess I'm finding the paint options bewildering. Please help to simplify things....

I've got hardly touched tins of oil-based undercoat and oil-based gloss (one Johnstones trade and one International yacht enamel-don't ask). So one option is to start with an aluminium primer eg Rustin's, which I can get online in time for the weekend, and use these.

But perusing wood finishes direct I also see there are also things like Osmo opaque gloss woodstain which I presume work a bit like linseed oil paint.

I suppose I'm wondering if I should stick with the 'conventional' primer/undercoat/gloss approach or shift to something quite different?

Our next door neighbour did his last week and found a few areas needing filling first. We both had our cills repaired at the same time a few years ago, so there's a possibility ours will be the same. Is there much difference in the bond to 2 part filler with things like this Osmo product compared with regular paint?
Cheers

I use nothing but Bedec MSP for external wood. I’ve not used it for windows as mine are UPVC with stone sills but I do use it for garden benches and for the timber canopy over the front door. It is water based and needs no undercoat or primer. It goes on easily but is a bit thin so needs 3 coats.

Yep, Bedec MSP. If you're unlucky you might need to touch it up in 15 years time.

Wow, that sounds almost too good to be true. If it’s as effective and compatible as they claim I can probably just strip the failed section of paint back to a good edge and leave doing a complete redo until things settle down, annual leave or some other mug to get up a ladder on my behalf.

I assume a synthetic brush given it’s water based?

After recommendations from this forum, I have just used bedec MSP on my uPVC windows and it went on really well. I'm now a convert to MSP and have just ordered a bunch of tins for various jobs.

It's been on for 1 week now, so keen to see how it holds up in the long term. I followed all the prep instructions, and used a synthetic brush. No primer. It is water based but I found it dried very quickly (too quickly) in the warm weather.

I emailed them about a couple of things, and they got back to me within a day, great service. (I asked if I can mix the MSP to the colour I need, without compromising the durability/performance, and they said it is fine)

I bought online from allfinishes.co.uk, full range, great price and free next Day delivery over £30.

Here's a pic. These windows were dark brown before, and needed just two coats on Soft Thyme MSP:
