Gave the VZ (Sept 2004 build) a wash and polish a few days back and found this "oyster" of surface rust under the factory applied paint. It is at the bend on the A Pillar and the door sill on the passenger front door opening. Most of the oyster was visually covered by the door rubber seal, so if it was there from day-one I did not notice it. On a close-up look, it appeared as a red centre, about 6mm diameter, with a "ring" of broken paint around it.
I scraped away at the paint and the damage area ended up about 15mm long. The rust had travelled under the original paint. There doesn't seem to be a chassis/sill lap joint around the rust area. The metal is dished in about 0.5mm. There is no obvious physical damage around this area, just this dimple.
The paint may have failed and moisture has got in, or moisture has been trapped under the original primers etc. and been painted over by the Holden paint shop "robots"? Thought I might share it with you if your paint looks bubbled or cracked in the pillar areas. Treated it to some rust converter, primer/undercoat on a cotton-bud and a touch-up coat with a small brush.
