Our house has 3 windows facing roughly south. All of them have paint flaking off the exterior window ledges although the window frames are otherwise sound. I remember painting all of them only 3 years ago, so they haven't lasted as long as I had hoped. The problem is clearly that wooden window ledges expand and contract and even crack in the Sun, made worse by our recent heatwave.

I see that one can get "flexible" paint, e.g. Johnstone's "flexible gloss" and others similar such as Ronseal "10 year external wood paint". They are obviously more expensive but might be worth it to avoid the effort of repainting every couple of years. Does anyone have experience of these - are they worth the money for timber surfaces in full sunlight?
