*nods* If a panel is fecked it doesn't matter if its really fecked...you are still going to replace it. Just makes it easier (and more satisfying) to remove!
This is the bit that's depressed me at times, cutting out part fecked panels to replace the whole thing to avoid patches on patches etc. But as said doesn;t matter whether that panel is part knackered or fully knackered you'll likely cut the majority of it out anyway.
