Originally I was going to use Ward for the glossy metals because it produces a nice satin type finish, but then I remembered this post on the use of BRDF's. So I guess I'll switch my shaders and use Phong for the glossy and Ward for the polished.
That's not how I understand that thread; it sounds to me like it's agreed that Ward is best for brushed metal. I don't see any difference in practice among the BRDFs when gloss is set to 1. I find Ward to be wayyyy better at satin metal than the others, but it's only really apparent on a big surface like a sink. I couldn't get phong or blinn to look good at all, but Ward did what I wanted.
Only comment I could make that hasnt been mentioned is I remember corten steel being made to intentionally rust. Looks really cool when rusted. Maybee they have a variety of metal finishes and te rusted look is just one of them (I havnt seen anyone here use it since uni )
i like the blinn glossies at 0.7 the best as it seems like a good compromise. ward is just too dulled out. I think you need to crank up the settings a bit though to remove the grain on the glossies
