Can I thin Floquil paints with mineral spirits?

Hi gang,

I'm about to put the finishing touches on my F-89 and was thinking about using my new bottle of Floquil Old Silver on it.  Two questions came to mind and I really wanted to ask everyone's opinion on it.

First, I've never used Floquil.  The bottle says to thin it with 25% thinner for airbrushing.  Can I use mineral spirits to thin it or is something else recommended?

Secondly, Do you think Floquil Old Silver will make for a good representation of natural metal on the F-89 or should I use something with more shine to it such as Alclad Aluminum or Stainless Steel?

I would really love to hear what you all have to say! 

Thanks!

Eric
