Oils, making dust, dirt, grime, etc on things like wing roots

[BlueNosers352nd]

The weathering on this Hellcat (Navy GB) is eluding me.  Didn't help that I wasn't really thinking when I sprayed Gunze Mr Color over my chipping layer.  Harder to chip that stuff back to the chipping layer.  Doogs did a great video yesterday on using oils on wing roots and what not.  I have now wiped my attempts off 4 times.  Everytime I try it and try to blend it, I end up with no texture or variations in tones (guess blotchy for a lack of a better term).  I know it takes multiple colors over multiple layers.  I'm wondering if it's too glossy?  The Mr Color went down so smooth and then with a gloss coat it's smooter than a baby's you know what.  Wondering if it isn't enough texture and that's why it ends up being so uniform rather than varied.

 

I don't have the ABT oils he is using, so I am using Winsor Newton Oils, which should get me there in the end.

 

Any thoughts?
