I just installed a new exterior door. I put the original, painted interior-side casing back on, but to make it line up properly I put some new, unpainted 1/4" trim strips (not sure what they're called exactly) between the door frame and the casing.
I need to repaint it all, but how do I prepare it? There are seams between the strips that I'd like to hide, and some small (less than 1/4") gaps in places between the casing and the door frame.
Do I caulk the gaps? Spackle them? What about the seams where two pieces meet?
