Will a door edge guard cause rust or other issues?

Question

I would like to place a u-shaped rubber door guard provided with double sided tape along the edges of my car doors to avoid damage against other cars or against walls.

I wonder whether this protection will cause water to be trapped and on the long term additional rust.

Answer 1

Less likely from the rubber than from a chipped edge when there is no guard.

Any damaged coating will give the metal chance to return to its natural state which is what it wants to do chemically...
