I just purchased a 29.5 and saw that the fiberglass within which the hatchcover slides (does it have a name?) is cracked and splintered in several places. Has anyone had any experience in repairing this? It seems to be one large piece and covers the lines going forward as well. It was really a design snafu because it's the perfect place to grab when you go down the steps and it has virtually no support. It seems to be mainly a cosmetic issue since the hatch closes well. I know that if I only fix the cracks and don't reinforce it, my guests will only break it again. Any ideas?
