Thank you again, and my pockets are not deep enough for super protection. The quotes I am getting are around $12/SF installed and I can live with that.

I spoke to one of the 3M sales reps and he indicated even without anchoring the film, it will definitely slow someone down intent on breaking in, your comments seem to confirm this.  

Thank you smartie2shoes for taking time to share your expertise and provide such a detailed answer, your comments are greatly appreciated and very helpful.

The main emphasis of my job is to reduce or delay breaking and entering through windows that are hidden from view of neighbors, my doors are reinforced with Mul-T-Lock deadbolts and door armour jamb kits so the windows are the next obvious entry point.  Especially windows that are somewhat hidden from view.

The film quoted is 3M Ultra S600.

I would welcome any other comments.

Hi Roach, the windows are about 20" W X 40" T, so an attachment would probably stand out. 

Hello, I am brand new to the forum and I would appreciate some feedback on a couple questions I have.

My house is only a few years old and has vinyl framed windows. I recently had a couple quotes from 3M dealers and they indicated DOW 995 would not be an option on the install due to the vinyl frame windows.  I assume this is correct since the film installers do this kind of job routinely and the DOW 995 would be an up-sell. Would an 8 mil window film install gain me any security or just make it easier to knock out the windows in one piece?

Would anyone recommend I have the film installed and then do a wet or mechanical attachment myself.  Is there a mechanical attachment that looks good in a residential setting?

The 3M installer(s) assured me the clarity with the film installed would not be noticeable.  Based on what I have read in various threads here the 3M film tends to not be optically clear. Has the film improved?  Will the clarity be noticeably degraded with an 8 mil window film?

Thanks for any advice.
