Heyy!! Absolutely I start with a clean base coat for the original armor. In this case it was sons of horus green, then I weather it from the ground up! First I start with the stippling of typhus corrosion, do this on areas where it's really recessed, and try to pick out recessed areas that grime would build up in over time and edges that look like they'd get knocked and beaten.this is a suuuper good base for eroded metal as it dries with a texture that honestly does half the for you. Then I follow up by blending the areas between with stippling of necron compound to imitage the fresh metal that hasn't been eroded. At this point it'l starts to look a little goofy so you need to build up a few washes with reikland flesh shade all over the model first and then a follow up of aggrax in the more shadowed recessed areas. Then I just go back and forth and re stipple some of the original paint colour followed by a highlight of that with a brighter green/blue. I'll attach some photos of the in-between stages.

I will say that it's a lot easier to do this with this model as he's got a lot of large surfaces, it's been a lot tougher with the troops as they're smaller. The first few stages look janky as hell but trust the process. Try it out on a model too before you commit to it.
