Replacing a 38 year old glass pane in back door (I broke it removing

Is there any convention/advantage for which way round it goes? Smooth
side in or out?
I can't detect any difference in the obscurity either way.
I am inclined to put the smooth side out - since the reason for
removing the old was pane (patterned both sides) was water
penetration at the bottom.

Geo,

Whichever side you putty will be the smoothe side of the glass - this
allows an easy finishing of the putty and ensures a good seal is made to
allow rainwater to run off the glass.

To get an even better water seal - when painting, allow the paint to go over
the putty and onto the glass by a few millimetres (do this freehand to form
a 'feather' edge and *not* using masking tape to get a 'straight finish).

BTW, the 'rule' applies whether the glass is fitted internally or
externally.
