Three hours painting this morning ideal conditions.Black gloss good,sadly cheap white gloss rubbish,not helped by a cheap brush.Sadly we don't have a good diy store near since Homebase closed.Wickes is coming instead.So back to cheapo shop and a tin of exterior matt white,it might cover the gloss,and some better but still crap brushes.So only the white security gate and white door frame to do,it might need another coat on Monday,i hope not.You need quality paint and tools otherwise you have do do it over and over again.This paint does not seem to have covering power i hope the matt does,i hate bodging.
