My family has owned this camper for many years. I recently tried fixing the cracking ABS roof with the MEK and ABS method, but the cracks continue to appear after a few weeks of being filled in. I believe the next step would be to rip off the ABS layer and use grizzly grip or truck bed liner paint. Any suggestions on this would be much appreciated. Another inquiry I had was about fixing the front body panel. My father had hit part of the camper with the lawn mower a week ago, leaving a large dent in the metal side panel, and a hole/crack in the front piece. For this, I am thinking about buying a fiberglass repair kit and patching the hole. I was hoping for advice on this as well. I attached an image of it.
