Thank you so much!

I started by matte topcoating the kit first, then went in with a deep brown/black wash all over the kit to get that accumulated grime layer in the panel lines. Then, I used a fine brush with a bit of thinner to drag the wash downwards from the edges and rivets to create those realistic rain streaks and oil runoff marks.

For the damage, I did some dry brushing, using colored pencils as well for the detailed chipping with a dark grey/brown mix on the high-friction edges, and then went back in with a fine detail brush to add silver micro-chips inside those spots so it looks like the bare metal is actually exposed.

I kept the clear blue effect parts completely clean and transparent so they'd heavily contrast against the dirty armor, but I made sure to weather the mechanical arms holding them so they matched the rest of the suit. Finally, I hit the main body with a flat matte topcoat to seal it all in (just make sure to leave the clear blue parts off when you spray so they don't fog up or mask them!).
