Hello, a bit of a new kid on the block, (Whose kidding, I'm in the Veteran Battalion). Been using Humbrol since it was eight pence, that's eight OLD pence, a tinlet. I'm a professional artist, and even mix it with oils now & then. Never liked it in the airbrush, tends to 'speckle on fine lines, simply because it is too coarse.
Just discovered White Ensign Colourcote, and it sprays like a dream.
I see that Humbrol seem to be reducing their range too.
