I'd like to know your technique so I can improve my own painting.
Technique is simple to describe, a terror to do...
Undercoat is Reaper's Rainy Grey. I just slap that on (usually two coats), and try to make sure I get all the panel lines coated well... Then the primary coat is Reaper's Misty Grey. This coat is where I start to panel paint, and also requires two coats to make it look good... After that I work up 2:1, 1:1, 1:2 and finally straight Reaper's Pure White.
So I guess 5 progressions, 6 if you count the undercoat.
What I learned from the original Griffin was to make the size of the grey area smaller, and use more white - where I had used it as a highlight color previously.
I prefer 20/0 or 18/0 spotters, but have gone as large as 5/0 (I'm the guy you see in the store, pulling the little protectors off the tips, and staring at the paint brushes... "Nope, this one has one or two strands out of place" <as I put it back>). The coat of straight Misty Grey usually takes 2-3 hours (assuming 1 coat) and is enough to make you want to gouge out your own eyes... But each progressive shade gets easier (mentally too)...
As for dry-brushing and washes... Don't normally use them... Maybe on the silver of the heat sinks... A little on the gun barrels.. But that is it for dry-brushing... And I seldomly ever do a wash.
That's pretty much it... It's slow.. It's time consuming.. It has it's limitations (scaled armor is an issue)... But I like the results.
