I recently used All Metal Bumpers at Ingleburn in Sydney and was quite pleased with the results, they did a good job on the diecast parts.
Some areas on close inspection could see some faults but I am not building a show car and the cost was reasonable when doing a bulk lot job.

Have a look at Tim Bartrop, he writes the Dr Tim column in Cruizin magazine and is based in QLD.  Contact details can be seen in the magazine.  He's a hot rodder who understands the modified car scene.
