Nattys Blue or Red for Metallic

[pfix]

I need opinions on whether Natty's Blue or Red would hi-lite the mettalic flake on a black paint and also a graphite gray. I have read the blue is best suited for dark colors but I was curious about the metallic paints and the difference in how red and blue will finish out. I am using Autoglym HD wax and I am happy with the deep wet gloss it provides but I would like to try one of Natty's waxes for comparison.,

Thanks,

Paul

I have used natty's red on dark red metallic paint, and love it. Looks very wet when done.
