Hi,can anyone help please, I am going to paint inside panel doors, I'm going to use water based paint, which looks the best, gloss or semi gloss, and what is the difference between semi gloss and satin, also the selection of whites is astounding, do most people go with pre-mixed whites when painting doors, the last house we lived in had varnished doors, so I've never done this before, it's also an older house. Thanks.
