I'm refinishing my grandmothers front door. It is metal (I'm sure) with a coat of factory primer (I think).
I stripped off the previous paint with a few applications of Citristrip. The primer remained completely intact which leads me to believe it is maybe some sort of factory powder coat or something that is impervious to strippers; either way its fine being on there - saves me from having to prime.
My question is, what type of paint should I use on the door? I hadn't really thought about it until I saw this video by TOH (https://www.thisoldhouse.com/how-to/how-to-paint-exterior-metal-door) suggesting the use of DTM or direct to metal paint.
Is this required? Will the primer effect this? When I think of direct to metal I think completely bare silver metal. In the video it is shown going over what I believe to be a similar finish to what I have after stripping.
Note: it seemed like the paint that was on the door before was latex-based given the way it came off (like peeling off a face mask/not in chips); held up rather well. But I'm not paint expert - all paints may strip off similarly.
