C5 small bumper crack
Hello,
I went to get a coffee at a local store, pulled up a little to far into the edge of the side walk (Still learning to park this things clearly), and heard a scrape.
I went back out to check it out, looks like a small crack maybe .5" down the side, right by the turn signal on the passenger side.
I know about bondo, but is there something I can use to just fill the crack? Now I'm convinced I'm going to park a mile away, plus extra cardio?

I use this 3M product to fix a crack in my driver front fender, which is also a somewhat flexible plastic (not fiberglass). Fiberglass repairs wont work on the bumper.
Try to apply some in the crack and use tape to hold it closed. It sets up in like 15min so work quickly.

You can get away with normal fiberglass repairs on a urethane bumper as a thin layer allows for some movement. But it will "pop" if hit at all hard. I repaired a pretty major crack in the flex bumper of our Subaru, by scuffing behind the crack, drilling a few small holes either side of it and applying a layer of resin soaked 'glass mat behind the crack. The resin pushes into the holes and they act like rivets. Then on the outside, just make a small groove where the crack is and use Bondo to fill the groove. Then sand and paint the area.
