spectral aluminum has a reflective index of 92 to 99.7 depending on the quality and the reflective surface is actualy nickel which will not react with the salt air so it just takes a simple wipe once and a while to remove the salt creep.

I will keep that in mind for my next build (when I have money to spend)

I found this product at the bottom of the page, the 12" by 24" @ US$14 would have worked for me. I think that is about 4x the price of what I used, but since i already had it the cost difference would be US$14
