Martin Brothers Painting does some kitchen cabinet painting and bathroom cabinet painting like seen on this page.
If there is a place to spray the doors and a place they can dry inside. This can take a lot of space so we don't spray them often.
We use Advance Waterborne Alkyd paint by Benjamin Moore.
Once this paint has fully cured it is as hard as the traditional oil base enamel.
The painting process for cabinets is not a quick one.
See below.
We first must clean them, then de-gloss, prime, sand, remove the dust then apply at least two finish coats of paint.
