What are people's experiences with using the one coat paints? I'm painting white walls (that have turned a little grey with age, haven't been painted for about 20 years). I opted for a mid range low sheen acrylic and have had to do 3 coats so far and I think I should do another.
Is it worth paying that bit extra for the rather pricey one coat paints? Do they really cover well with one coat? They seem to cost about 50% extra.
