It just goes in phases,
Right now you see more people going for nonmetallic metallics,

But mainly you are going to  run into people who shy away from that sort of effect because it is too easy to acheive,

Just like dipping can carry alot of looks of disdain from some groups of people,

I personaally havent done it but I think it is a good way to speed through masses of troops,

If you are talking about the red/blue transparent paints that tamiya has ( I call them glass paints)
I love them, but people did tend to overdo the gloss look,
Even tyranid models on drool gloss is shyed away from,

Personally I never cared much for wide spread use of the technique because it brings to attention that the model is just that,
A model

The non metallic style offers more realism, and thus is more decieving, Takes insanely more time,

This is a 25mm figure that is painted silver would look like poop,
But instead hes painted as if he was silver,

And thusly looks outstanding,

I hope that helps,

And have a great time whatever you choose to do.

Well the way that I hav e seen them in still limited use is to do the glaze, then go with a little black wash, very thinned out,
This cuts down the shiney plastic look a bit and gives it more shadow,
Just a thought for mouths and the such,

Good luck to you and I look forward to seeing them,

Also, it's a well known fact that painted miniatures hit and save more.
