Choice of thinner, medium and basic procedure?
 

I thought it would be fun to share basic mediums, thinners/brush cleaners and basic proccrure.

So in the spirit of I'll show you mine if you show me yours:

• I use Gamblin Neo Meglip as my painting medium.
  
  I use Gamsol as a thinner/brush cleaner.
  
  I build my painting in thin layers, each layer being painted alla prima with little or no glazing. I do, however, employ scumbling.

Sure, No Problemo...
 

I use two mediums:

Undertones - Gamblin's Galkyd Lite
Color - I use the following medium:

5 parts Damar Varnish
5 parts Rectified Turpentine
3 parts Stand Oil
1 part Venice Turpentine (Sennelier)
1-2 drops of Cobalt Drier per ounce of medium

I paint my undertones in grisaille or verdaccio or both using Mars Black, Flake White, Chromium Oxide Green.

I paint color using glazes in darker areas and opaque painting in lighter areas.

All is done using a controlled palette of paint based on value.

I final varnish with Gamblin's Gamvar.

I clean my brushes in odorless turpentine and soap and water.

Currently testing: Walnut Oil/Alkyd mediums and Walnut Oil/Stand Oil/Alkyd medium mixes.
