Hi, look like my trunk floor has a 6" long crack in it. Someware along the way sombody has put a beef up plate for the right side upper shock mount. This is ware the crack started. Wish they have a least stop drilled the crack. Is there a way to fix the crack with out welding it? Also how do you clean out the drain for the cowl/heater box, and were is the drain? Thanks Tony
Fiberglass is fine to repair leaks but you can't use it for structural areas like the shock mount. Stop drill the crack, weld it up and then re-inforce as necessary to keep it from breaking someplace else in the future. If it has already been reinforced then use a backer plate on the underside held in place with steel pop rivets and epoxy the topside to seal it.
Oh, man! Did I ever misread the first post (traumatized by having breakfast with Frank). Gotta weld. You may want to use the method I posted about afterwards as a reinforcement procedure.
