As a distributor of XPEL paint protection, we have added this DIY product to protect your door edges.  XPELs Door Edge Guard is made from rugged clear polyurethane plastic.  With a great clear coat, it has a maximum shine to match your paint making it invisible from 2 feet away. Have you ever have a passenger open their door too far into a garage wall, or maybe even into another parked car?  This will prevent your paint from touching that wall or car.  Preventing that paint chip or scratch. Simple to install and plenty to do all 4 doors.  This has 12 feet. The last photo is a link to 3M's installation video.
