what material is a good reflecter made of?

Heres the deal,I just ordered a Nova Extreame T5 set up for my new 30 gal. tank. I have made the common mistake of researching after my purchase and see now that the reflecter is not so good.
I am a sheet metal worker and can make anything i want.i would like to replace the single reflecter for individual ones right off the bat but i don't know what the best material is.mirror polished stainless?polished alum.?or brushed alum?
I know the best design is a rounded M shape just not what to make the out of.If it works out good I'd be willing to help out other reefers retrofit their cheap hoods with them.

This place sells spectral aluminum ( all the way at the bottom of the page)

this is THE stuff , much higher reflective than polished alum or the wrisco.
