I can't get a fine brushed stainless steel image!!

hello, and thanks for waiting. I had a 1 week break.

Well can you tell me more ?
wich method are you using ?

What kind of lighting have you setuped ?

you can try the option "interpolate glossies" into SR options if you use irradiance map method, take less time and there's no grain at all, but glossies are interpolated and less precise. But it can be a way to go !
