I don't know about Platinum but I have recently started coating finished gum
prints with acrylic glossy varnish. I have tried various dilutions but find
the effect is best with the stronger dilutions. Clearly the paper you use has
a significant effect on the degree of gloss.
BTW, when you put the varnish on it has a white opaque appearance which
initially worried me but the varnish does dry to a clear finish so don't
worry.
