I didn't have very good results with the subbing layer mentioned. I had problems with base wringling when the subbing dries.

I had great results in "subbing" POLYESTER with corona discharge. I used a commercial corona unit and also made one by myself as shown here: http://www.youtube.com/watch?v=StgbV766dqQ . However, it broke down for an unknown reason and when I was repairing it, I got a jolt (just 230 V ;D) and left it alone for a while. I'm thinking of designing an easier-to-build, smaller and safer alternative... When it happens, I will give instructions to build one.

The result with corona treated polyester, coated with coating blade, was nearly perfect. I shot it in medium format: http://www.students.tut.fi/~alhonena...ga_1200dpi.jpg and as you can see, the rate of defects is so low it could be done in 35mm.

However, if you are going to coat 35mm leader, you will have a problem with emulsion running to the perforations and off edges. Thus, you should use a bit wider film without perfs, then cut it down and perforate after coating. I have presented an inexpensive way to perforate 35mm with "good enough" quality for still film use: http://www.apug.org/forums/forum205/...rate-35mm.html
