Ok so, the blue being inside the shackle bushing tube and under the bump stop, while seemingly unlikely, could be explained away if they were indeed removed for a paint job. But how does the blue get under the factory undercoating?
Has there ever been a case where a car was painted a color, perhaps the wrong color, on the assembly line, then ran though the paint stage once again when the mistake was discovered? Then once the correct paint was applied, in this case the gold, "then" the undercoating, bump stops, shackles, etc,...were applied or installed?
