Hi,
I have just picked up some custom sized rebated Hume double doors which I ordered through Bunnings. I paid for them to be primed but was surprised to find that the decorative, recessed area on the face is not primed and appears to be exposed MDF (see picture) as it has a corky feel.
Would it be ok to paint this area with the same oil-based primer that I am using for the rest of the door? I'm a bit disappointed to be honest, as this recessed area will never be truly smooth
Thanks in advance.
