polymer film that is resistant to fluorine etching?
(OP)
I am looking for a solution to our etched glass problem. Currently the flourine gas being given off in our plant is causing the glass (particularly that of mobile machinery) to become etched, making it near impossible to see through.
Does anyone now of a particular kind of film we could use to coat the glass with so we are not constantly replacing it?

Fluorine is going to be tough on transparent materials of any sort, if there's enough around to etch glass. You may get more transparent life out of a polymeric material than out of glass in this case.
Correct me if I'm wrong, but fluorine isn't really the issue here, it's fluoride ion. Perhaps a polymeric coating on the glass would do the job. Most of the coatings will be permeable to fluorine gas, but as long as they're not permeable to water there won't be anything to solvate the glass and carry it away. A wax may be sufficient for this purpose.

My biggest concern is the personnel exposure to the fumes that are etching the glass as posted by btureblood. The damage done by fluorine and it's products is insidious in that the body has hard time repairing the damage even if one is removed from the source. We had to abandon a very efficient process because of the problem with HF fumes.

I am not sure you still looking for the film material that will help in a fluorine environement but an excellent material that can be manufactured into a film pyrolytic graphite. This material is impervious to corrosion of F2.

I honestly don't know if it's resistant to HF or F, but it's resistant to everything else, and you can still see through it.
