Hey guys,
This is my first post

I was just wondering whether anyone has any experience removing rain guards from the driver and passenger windows?
My ford falcon xr6 has one above the drivers window and originally i though it would be easy to pull off however it is a little harder than i first thought.
I heated up the glue with a hair dryer and tried pulling but nothing happened except a little crack...oops
The car is 9 years old and the rain guards were installed as new so i guess it would be pretty stuck.

Also, does it leave a mark or anything or will i just be able to remove the glue with some alcohol or something?

Thanks in advance
