I know the time to replace them will vary, but how long do you guys usually leave it on for? Mine is starting to get to the point where it needs to be replaced.

Also, how do I remove this? Specifically speaking of the one on the front end.

 

I used 3M clear bra and it has been on like 2.5 years now and still looks new like day 1. Mine has lifetime warranty I believe.

Depending on the brand you use, you should have warranty and they will replace it for free. Let the professional do it right.

 

It's a tedious process but you can remove it using a heat gun/hair dryer.

Simply warm up the area then peel it off slowly

 

you peel it off.

 

Slowly heat it, slowly peel..try an area that wont be seen as easily..
