I have just stumbled across this YouTube channel.
https://www.youtube.com/user/PhatWOP001/featured
By a guy called Vince Venturella.
Full of interesting little nuggets of information. I’ve just watched one on oil washes which makes me want to ditch my Army Painter Quickshade which has been my goto solution for just about everything.
Now to find time to watch the other hundred or so videos.
