I have always installed them on the panel first. I put the clip in place and then push the center pin in to secure it. I try to have them aligned properly but even after being installed they can be rotated for that final alignment.

I then position the trim in the correct position (front to back). It is not so easy to adjust after it is started on. I hook the top edge of the trim piece on the top back edges of the clips (or at least as many as I can.

Then I strike the trim with a mallet on the first clip. It snaps into place. check for correct positioning and move on to the second clip and strike it. Keep moving back and as you go see if you can get the trim started on the top of at least two clips back from where you are working. Never "set" the bottom of the trim on a clip if it is not already started on the top of at least the next clip in the line.

If the back edge of the trim is corroded at the point where it is supposed to grasp a clip you might consider leaving that one or two (or even three) out. Actually every other hole equipped with a clip is enough to hold it if it comes down to that.

A little soap on the clips is not a bad thing for some helpful temporary lubrication.


Good luck,
Randy
