I've been looking for a proper rain tray for my '72 for 3 years now. My original is cracked beyond repair (which I attempted with epoxy - lasted maybe 2 weeks).
I was told some time ago that they used some sort of specialized moulded plastic for these things, and that no glue, bondo, etc. would adhere (could be bogus, but don't know). Has ANYONE had any success in rebonding small cracks (1/2-1") in these things? Pat |

Many of the plastics shrink as they age, hence the cracks. Some of the softer plastics like PE and PP are very waxy and basically glue will not stick. It is almost better to get another bad one, or at least a section of it, to use as a donor for a fill material. Then it is a matter of 'welding' it in. Better to practice on the donor material first to develop the process. You may find a hot air gun better than a torch. You do not want to work directly with a flame on the plastic since this will cause a lot of degradation of the plastic, and thus more cracking shortly thereafter.
