Gloss vs Dull finish...

Whether to use a Glossy Finish or a Dull Coat Finish is truly a matter of personal preference.  Tecnically one is supposed to use Dull Coat on most metal, and Gloss on most plastics - this is the standard, but you will see them mixed.  I suppose if one is using them for wargames or presentation, this code of style might be more the norm and expected, but beyond that, for personal use, I say do which pleases you.

For myself, having experimented in both, I prefer the Dull Coat to a Glossy Finish.  I think the Glossy gives a collectable look, but in a "toy like" fashion.  On the other hand, I think the Dull Coat gives a more realistic look, and in some cases, more life-like detail.

Here are a couple of 1812 period pieces I have done, Isaac Pearson and Nathaniel LePratte, both in a Dull Coat finish.  Compare this to my last post, Percival Craddock, which was done in a Gloss Finish, and you will see why my preference is a Dull Coat in everything.
