Equivalency to 32 micro -finish

Please advise on what a 32 micro finish would translate to in SPE#. Is this a light polish? Your help would be appreciated.

Thought someone else would answer this; however, if you are still looking for a partial answer, this is what I can give you. I have no clue what SPE is; however, a 32 RMS is basically the surface finish you get on raw bar stock materials and sheet metal from a metal supplier. The visual surface appearance does not necessarily have anything to do with RMS. You can have very rough bright parts or very dull smooth parts.
