I've made up a prototype door out of MDF for a kitchen project...the loose tenon kind described in another thread recently. Making the door has been the easy part, how do you hold/support the door for painting? Doing one side at a time and letting it dry is very slow and tends to leave the paint a little thick on the underside edges. I'm brush painting the door lying flat, as I don't have any spraying equipment...not sure how MDF primer would spray anyway as it's pretty thick. Are there any tricks or tips as to how to do this or do I just need to be more patient?
