In reply to Frankie boy:
As it wasn't your fault, I'd expect the other party to make good your loss. It may be that a rock on a wire doesn't show any damage, but what will it do for your confidence? If you have to rely on that, and you're not 100% certain its up to spec.
Put in an itemised list of everything, including rucksacks and technical clothing etc that may have been covered in water/antifreeze/fluid from the other vehicle. Ideally you'd want everything to be in the state it was before the crash. Don't accept the first number they give you. If they let you keep the old kit, mark it up with a different coloured tape and use whatever, where you think it is safe to do so, and dispose of the rest.
If they argue, then suggest you set up a 50m ab for one of their loss adjusters on the faulty kit.
