Could have been an "age" thing . I notice a lot of younger guys have a reliance on Brand Name products and have no idea how to use everything and anything you can find around the house or at your local hobby , art supply or hardware store . IRC Vallejo or MIG or somebody is releasing some kind of acrylic weathering pencils ( dirt , grime , rust , etc ) , should go for about $9 each at the LHS . You can get the same type of thing ,in about 50 more colors at the local art shop for about $3 each ! Where would you get yours from ?
Before I got involved with a bunch of fantasy gamer types I had no clue about GW paints , all the bright colors are a little off putting to us WW2 modeler types , but seeing up close what can done with them ,I changed my view of them . If I ever decide to paint fantasy figures , they'll be my go to paints .But I do use their washes regularly , I just wish they had sample sizes of the more colorful washes and inks ( reds , oranges , lime greens ) sort of like the little paint pots you get with the starter Airfix kits . Bit of a bummer to spend $6 or more on a blue wash or ink that doesn't work like you think it would . I end up giving them away ...
