yes, the scratch I p-tex'd was a core shot. The gap in the die cut base is very small but i'm afraid it will widen or moisture will get in there then freeze and expand.
Got it. You want to cut out the old repair right down to the core. There will be no harm in cutting just outside the old repair. You want to make sure that you get out all of the damaged base edges at the die cut seam. If these are not perfectly bonded to each other and the core then they can/will allow moisture through to the core. Once you have a clean wound you can under cut (angle cut) the edges of the gash. Then base material can be added. Base welds at the seam of a die cut are not easy and can cause future problems if they are poorly done. I would highly suggest bringing this one to a shop that has the gear to do this.
