For all of you lazy types who hate inking models...this is a cool product line.
I picked up the Quickshade Dark last week and find that using it is approximately 98% less effort than inking, with 104% better results.
I've used two methods:
A) Full dip (paint the model, dunk the entire thing in the goop, let dry).
B) Paint the stuff on with a brush, let dry.
I found that method A covered a bit of detail but looks 'acceptable' - and still better than hand shaded or inked (note: I am pretty good at both, not great).
Method B took slightly longer than a simple dunk and forget, but really looks great. It takes maybe 45 seconds to do a single 28mm miniature this way.
Downsides to the product:
* It takes 24 hours to dry. To me, not a big deal. I have models that have been waiting for shading and inking for...10 years.
* The Dark hides some detail over lighter paints if you just dunk them - the stuff is THICK. The STRONG version of Quickshade is what is recommended for 40K miniatures, but I had been using black ink, so went with the darkest one. The medium pigment STRONG version would probably not have this problem.
* If you don't like a glossy finish, you need to hit the dried models with a dull coat spray. The one this company makes is better than GWs, by all accounts I've seen. I like a glossy finish for this army, so this is not a problem for me.
* It seems expensive, but if it came from GW it would be at least twice as much, without a doubt. To me, $25+ is well worth saving an estimated 15-20 hours hand inking/shading little men with guns.
