Yep i colour coded mine and put them back on as the paint was slightly dodgy on one of my panels due to previous work. But depending on how new or how good the condition of your car is then you shouldnt have any problems when taking them off. Just heat it up with a hairdryer and pull. Then get scrubbing at the glue lol.
Yeah when i took mine off the door was indented by them that's why I put them back on. Either way My car is only half colour coded as it's a 94 model and I want to keep the originality of it but with those ones they look better colour coded. Mines a very thin flat strip
