Get a plastic set of door panel removal tools. You can use the plastic pry bar to lift up the air covers. You may have to also put sticky tape at the top of the doors not just the front pillars.

 

Also, never use an Xacto knife or razor blade on a painted surface. You can use one of the plastic scrapers to remove most of any remaining tape residue and then an alcohol hand cleaner to remove the rest. Acetone will soften and hurt the integrity of your paint and clear coat.

 

FYI - I didn't use an exacto knife or acetone on the painted surface but on the plastic pillar pieces.

 

I wasn't suggesting you (Man1nBoat) did. I was just trying to clarify to other member what surfaces to not use it on.
