what do professional painters use on skirting to get the best finish. Ive fitted new skirting and door trims to all of my house and painted some. Ive found that gloss gives a nice shiny finish but doesnt stay white for long and goes yellow, or ive used egg shell which is a lot whiter and stays white but is duller and you can see all the brush strokes. Please advise which is the best paint to use for the ultimate professional finish, thanks Rick
