More practice, perhaps. Or more patience...
Thanks for the thoughts

Both would be my guess. I have been weathering stuff for over 40 years now and I'm still learning. If its a particular effect I'm trying to achieve I will often practice on a few items form my scrap loco/rolling stock collection (which I have for the purpose) until such time as I feel confident to apply it t the actual item.
There's no right or wrong material to use with weathering. Its the end result that counts.
I know modellers that wont use anything but enamels because that what they always used, likewise I know others that use oils or inks. Whereas I favour acrylics with water (or water with a touch of car screen wash for some brands) as the thinner if needed. With powders, chalks, washes etc for accents. Both there again I favour automotive paints for the main colours...….. which horrifies some.
Yet all our models look fine when seen together.
Nor can the process be explained mathematically as if baking a cake.
A list of colours is one thing but lightness or heaviness of hand in applying them, cutting back etc?...… comes with experiment and practice.
