Sorry for the late response.
Here is something to
read, but even if you dont, this is something I teach everyone at our painting clinics at my FLGS:
Quote:
"Gunk" is a combination of water, flow improver, and drying retarder used by some painters to dilute their paints (at least one drop with subsequent drops being just plain water). Formulas for "gunk" vary: I use a formula once (and possibly still) used by Anne Foerster of 5 parts water, 4 parts flow improver, and 1 part drying retarder. I have my "gunk" mixed up in a spare Reaper MSP bottle (3 empty bottles for $3).
I use Reaper and Vallejo paints equally, because I cant stand paint pots. Dropper bottles allow easy measuring, and since I use gunk in almost everything I do, I want to measure it all. I also use GW's primer but have recently been experimenting with Army Painter's colored primers as well. Reaper makes all the additives mentioned above.
Keep your paints thinned (gunk excels here!) and that is the single most important thing I can pass on!
