No one modifies these pre-colored photo etch parts? They looks so new and perfect...I would just feel safer trying a technique that someone has had good luck with. Scrapping away paint is a nice idea (to show wear), but most certainly is permanent solution. Dry brushing or a (weathering) wash add a nice "shadow" relief...depth to the cockpit panel, when I'm painting a part from scratch. IDK...I don't wanna mess up these nice parts, but they looks so perfect (lol)...
If anyone has any thoughts it could be a help....thanks
