Can the ceiling paint on the ceiling?
Brush paint can, but must be painted, the effect is more impressive. If the surface of the oil, then, first clean up.
Aluminum buckle board is not good brush paint, if there is temperature and water vapor is difficult to use long.
Is possible, but now we look in appearance to look better, will choose to spray the aluminum plate to install, do not have their own to brush.
Can not. A long time will fall out
