Rust Bubbles Behind Front Bumper...

Flash's lovely early bay from Cali is showing a few UK weather blues. Some rust bubbles behind the bumper have appeared, so we've ground it back to find the extent of the damage. Looks like it needs an inner and outer lower repair panel. We even found an 8mm Facom spanner with an 8mm nut and washer inside the panel! Looks like somebody dropped it when fitting the ariel years ago! However you must remember this is the effect, not the cause and we've got to find out how the water's got in there. Either from an old windscreen leak, or present day leak. We're going to have to remove the screen and look for water ingress.
