nickel is non reactive whare silver is reactive a little. I could scan a metal reactance chart from work but i would have to find one

for this reason alone the nickel finnish would be mor durable in the enviorment we use it it. I cleaned my reflector [nickel one] after 6 months of abuse and it looked like it was brand new, my old one [silver one] and it looks aged, the nickel one had more salt on it. so from experiance I can tell you the fin ish does matter but it is up to you to decide how much. I think if Delphinus can rember whare he got the price from it was like 3.50/sq ft [1/2 the price i can get it from on the island

] so it is a cheep reflector at that price.
