What will you call it?

"Patpur's No Ding Door Thing?"

I hope it works for you. A couple things to keep an eye out for though:

1. Some people may think that the protection is there for their convenience and open their doors even harder into yours which could still cause a dent. And,

2. You still aren't well protected against dings from doors with edges that are longer on the top than on the bottom (such as another Crossfire). For example, a pickup truck typically has a squared and vertical door edge. It will contact the point on your door that sticks out the furthest, which you can easily protect. However, many car doors, and in particular rear doors, will contact your Crossfire door much higher than where the No Ding Door Thing is currently covering.
