We did a project in Northville Michigan that was hit by a runaway car. Check out the images below which show the process of the repair. From the original damage to the finished product. You cannot even tell a car ever hit the wall. These four images are actually a small sample of the actuall process that took place. There was some light carpentry work, liquid moisture barrier, starter track, sticking of the foam, several coats of fiberglass based cement, top coat and finally paint.
