How do you keep your prepass stuck to the window?

I have also read lately that gorilla glue also makes an excellent hair spray.
Although I should probably mention that it has been proven to be possibly permanent when used in that application.

 

Originaly Prepass boxes come with strips of
3M™ Dual Lock™ Reclosable Fastener .

 

Omg, really?

do this in warm weather or with a warm windshield from say a hair dryer. First clean it, I use alcohol prep pads, then dry it off >>>> making sure it is dry, then put the thing on the windshield applying pressure carefully but firmly for 30 seconds to a minute.

from all the ones we get, using that same method we have had zero fall off. For that matter, I am staring at my beater truck with a easypass still attached and it has been there for 17 years.

 

Heavy duty Velcro, makes replacing the batteries a lot easier.

 

My prepass just sits on dash , windshield was replaced and the velcro wasn't reusable so I just leave on dash. Works everything never had a issue.

 

I used the clear velcro that came with the elite pass clean window put defrost on high let it sit in the sun at the same time to make sure window is humidity free and warm. Get some rubbing alcohol and a napkin clean window where you want it stick it and press. Done mine is on now 3+ years only original velcro holds it on and i can pull ezpass of and velcro stays on window

 

I put mine in the little compartment above my head. Those radio waves go through plastic just as easy as they do glass.

 

I tried everything and Gorilla Double Sided is the way to go.

 

This.
The less things stuck to my windshield, the better.

 

This is the best answer. That stuff is the best. If you want to mount anything securely and strongly but have it be removable there's really no better. I've run into a situation where they couldn't read the ezpass and I had to physically scan the barcode on the tollbooth.
