I will be painting a door a gloss colour called Cashmere dream(if that means anything to you) which I can only describe as a milky coffee colour, bordering a darker beige. I have coated the door with 2 coats of white primer undercoat as it was bear wood and was wondering if you think I should use a normal white undercoat before the top coat or will it show through. A light grey undercoat may even be too dark, I don't know. Any suggestions? Thanks
