Well I got the job done,this was the least favorite job I have Ever done to say the least. Now they want 10 more installed. the first job was 34. What I have found installing this film is that the amount of slip that they recommended will not work on all types of glass, as you all know film will react differently on different glass, as far as sticking faster. I ended up using more slip on this glass, it was 1/2" then laminate and then 1/4" because the rooms were conference rooms so I imagine the glass used was for noise cancellation. I also used some llumar cdf film slightly larger than the film installed for an overlay so not to scratch the non hard coat Casper film while installing, this film scratches by almost just looking at it,if a hard coat was used on this film it would not work. As far as pre-cutting this film,I cut all of the film on a glass table and made several passes with a new olfa blade with very little pressure till i cut through the film to get a decent edge. rolled the film up with the liner side out with a min 3" diameter. Sure wish I could post some pics of the job, however when i try and post pics on here it says the file is too large.
