There are far better mixtures of acids than sulfuric/water for electropolishing. The temp and the amperage depends on which one you choose. There are many sources for this information. One of the highest recognized in the USA was Charles Faust.

You can search on this site or on a search engine like Google for "Electropolishing". There are MANY firms that sell good electropolishing solutions. 80/20 sulfuric/phosphoric is a favorite of many, but some of the commercial formulae are better.
