YOur mistake was using an over the counter resin system like polyester or isothalic. MEKP is nasty stuff for the amatuer and those store resinshave additives to make them have longer shelf life and that translates into weaker bonds and the incomplete curing you speak of. Most likely, you didn't use enough catalyst(MEKP) and it may never fully set up. I would start from scratch and either use a good quality epoxy(Gougeon Brothers, System 3 etc.) and then your repair will be stronger than the rest of the bumper. Ask Mike Cullom about my kevlar and Gougeon Brothers repair. DM&FS At 11:54 AM 8/25/2007, Jeff Lincoln wrote: >Ok so I finally got around to fixing my cracked bumper.
