>>8754716Thanks anon! I recommend getting some Vallejo airbrush thinner. My process was to basically spread the wash (I also use a Vallejo premade wash for convenience) all over the body, getting in all the lil books and crannies and let it set.
Then, I dabbed some of the airbrush thinner onto a paper towel and proceeded to basically wipe him down, but not scrubbing him clean. The thinner removed much of the excess wash, keeping it just in the crevices and my taking it easy with cleaning him also allowed the darker tint to the green from the wash to stay.
Beyond that, you'll want to probably get a topcoat. I like Tamiya TS-80 flat, personally. Wait for what's left of the wash and any other painting you do to dry and set for a day or two. Then just coat him with the topcoat (you want to spray him I a way that you're mostly spraying back and forth from a distance, so the falling spray lands on him, rather than just trying to apply DIRECTLY.
Let it dry and do one or two more coats. This will keep the paintwork and wash safe and sealed while also making him nice and matte, losing the plastic gloss.
Just take it slow and easy. Don't be afraid to fuck up. That airbrush thinner is perfect for also removing all the work you do, if you decide you went too far and want to start over.
