Back at you brother. It's all about terminology and it is often confusing. There is a glaze as a type of paint and then there is a glaze as a verb. There is a wash as a type of paint and a wash used as a verb. But let's quickly simplify the difference between a wash and a glaze, because some were pointing you in the direction of inks and washes (another misnomer).
A wash is sufficiently diluting any paint and breaking down its surface tension and viscosity such that it naturally falls into the pits and recesses of a mini. Very often people will base coat something, wash it to create shadows, then repaint over the higher points with the same base coat. This is sort of the GW way of applying shadows. But you won't be applying washes too much to shade if you choose juicing to blend. Washes are normally applied very liberally, almost drenching the model in the wash to achieve the effect. There is also a "pin wash" which is pin pointing more accurately where you apply the wash. I might do this if the cracks I need to shade are too small to paint normally. I like to do normal washes, the type where you just spread it about willy nilly, on my bases.
A glaze should be more watered down than a wash. This is because it should have less pigment, since only a slight tinting is required both for juicing and tinting. Often times the consistency required is referred to as dirty water. So think about how you coke looks at the bottom of a glass of this beverage where the ice has completely melted. Some call this a 6x1 ratio.
A real quick aside. Diluting. I do it like this. If I want a 3:1 water to paint ratio, I'll dunk my relatively big mixing brush (because you don't mix your paints or dilute them or do any other tasks with the brush that you are using to paint). Submerge the brush in your water or medium, and quickly shovel it onto your pallet 3 times, wiping the brush onto the pallet in between each refill. Do this three times, then grab up the same amount of paint and mix it with the water or medium. That's it. Just consider a brush full of water to equal a brush full of paint.
Many painters to glaze simply to tint, though. Take a look at Ten Ball's work. It seems like he glazes a lot of his armor and weapons with a orangey-brown color. This adds interests/age. Now look at NMMAndy's last model. He glazed a turquoise color into the armor with beautiful results. These are the traditional forms of glazing, and very often what people mean when they use the term. The GW glazes are useful for this. But again, they are just odd colors. Their red glaZe, for instance, tints things an awful pink red.
The video explains the second means of glazing. Juicing, we will heretofore refer to it. Beware, that video may have a part 1 to it that I missed. If you google video NMM sanguinor it will populate.
Gw gw now sells their paints as a set using their stupid way of painting. It's goes base coat, layer1 layer 2, wash, dry brush on edge highlights, glaze. Their "glaze" is actually meant to change the starkness of the highlight and better unify it with the layers. But it really only succeeds in altering the color in a negative way. RE TURN TO STORE.
Honestly, Digga, we both live Stateside. I honestly wouldn't mind showing you some things via Skype or talking you through things on the phome, if you traded me some sculpting tutorials. Hope this is helpful to you and others.
