If they are like the ones that I fitted last spring, they come pre drilled and with the shiny side protected with white film.
The job was not anything like as bad as I had feared, in fact I put it off for some time before I plucked up the courage to begin.
Actually was very straight forward to do. I began at the door hinge end, used my hands to shape them and fitted the tacks (not right in in case any needed to come out!) as I moved along. Main thing I had to watch out for was moving off line. When I got to the door catch I think that I had to use a mallet and wooden drift to get the profile to go into the corners (and I think that there are pins right in the corners which were fiddly to fit).
Overall it was much easier than I expected, and I didn't end up with unwanted creases.
