Do I or don't I...........?  Group: Members Posts: 5,899 Joined: 24-March 06 From: SE PA, near Philly Member No.: 5,765 Region Association: North East States  |
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 |

Ok guys...
Glue basics.... A glue joint is no better than the surface it adheres to..... If it is dirty or a fingertprint, your glue joint is sticking to that. Raintrays are flexible, epoxies like JB weld set up hard........ Hard patch on a flexible material means breakage...... You want a flexible patch with a little give.... Try a urethane adhesive or mebbe the flexible silicone stuff for guing mirrors.... Some plastics like the polyethelenes are almost ungluable...... They sell some coatings that can enhance the surface to improve adhesion but they generally are worthless..... Sheets or patches work well- crappy adhesion over a large area equals a working seal.
