I knew instantly that it needed another coat.  I ordered 3ltr of primer last week and rubbed it down today, alas no pictures.  I also rubbed down some other bits and pieces that need primer such as the bracket that the dashboard mounts to and that the steering column goes through.  I did get the car outside and found a few areas that hadn't received any paint so brushed those with paint in advance of the new spray session.

During the last few weeks I also applied some filler to a few areas that looked very distressed having been painted.  They look better now and will, I hope, look much better tomorrow when it is repainted.
