GO or Protective Spray?

I am printing with the Neutral ink set on JonCone Type 2 paper. I would like to protect the surface of the prints as much as possible, but am unsure as to whether GO or something like Hahnemuhle Protective Spray would be better for that purpose. Your thoughts?

I suggest Hahnemuhle Protective Spray for Type2. GO makes this paper have slightly less dMax. However, on some other papers (Crane Portfolio Rag for example) GO will make a deeper dMax. Both GO and HPRspray protect from out-gassing, pollution, and sun, but will not protect from scuffing as much as people want to think.

best regards,

Great- thanks for the quick reply, Walker!
