Back to this project again! I delayed doing it.

I got some advice from my mom and it seems very sensible to me. She says
she's done this many times and the trick is a fine grade sand paper then a
small thin brush to apply the paint. Smaller the better as wont show brush
marks. No spray paint.

She uses Latex but has no particular brand other than she's partial to
Sherman Williams for exterior (Thompson's water seal for wood things).

Any other tips? I do not plan to remove the door to do this. I do plan in
2 years or so to have the door and frame removed and replaced with something
nicer (It's the cheapest all white steel prehung done by renters when they
kicked out the nice wood one I had).

This is no job for a novice. You should ask Mom to come over and
demonstrate this time. Promise to take copious notes so that the next
time, you'll be able to do it yourself.
