Passenger car Window Film

Go to office max and get some transparency sheets. You can get them at the copy desk. I use em to as window glazing in everything. Cut it to size and glue it in with white glue

Hi, a big time thank you  for your suggestions. Thank You and All the Best  Bill Boise Idaho

12 passenger cars would be like 2 dozen packs to get enough to do all of them. Its cheaper and less fattening to get the acetate transparencies. Thats a really good idea tho

Blister packs are everywhere and you already paid for it once.

I like to use microscope slide cover slips.  The look like real glass, because they are

Yes, once upon a time we used overhead transparency film - boxes and boxes of them and I think I still have a few boxes of them for use in ink jet printers.

Those should work - could cut them into strips and secure with reasonably ease.  Probably could also Dull Coat them as well for the frosted film that you want, too.
