I second eleanor's motion. I tried a bit of this paper on a monochrome image on my Epson 4000 printed with ImagePrint. What small amount of bronzing there was disappeared with spraying.
Even at $15 per can, it'd take quite a few cans to equal my 4000-->4800 upgrade cost in spray alone.
BTW where did you get the paper? inkjetart.com, my usual vendor, won't have it until May.
