This is a Star Destroyer from Star Wars. Hot Wheels started releasing ships with a huge amounts of detailed form, without the detailing textures and values. Cost-cutting, but also could be better!
Easiest thing to do is to lather it entirely in a mixture of oil paint and taltine (an odourless thinner), so that its runny properties gets itself in all the tight grooves and corner.
After it has period of time to settle, we can begin wiping off surface stains and keeping the grooves coloured.
Once all wiped, we have the final product.
I even took my colleague's Millenium Falcon and gave it the same treatment.
