Glad I found this site. I learned the hard way with custom-cut light seals. The strips were all too wide, causing them to tilt and the adhesive to stick out and to the sides.
The method described on this site seems more difficult to apply, especially cutting the narrowest 1mm strips to the correct width (Nikon FE, door edges), but hey, you don’t have to do it every week.
