And I still have questions about doing the dirty wash over the whole tank... I have some acylic black now... Ive never done a wash so.... This is how Im planning it:
Highly diluted black paint, and while using my small detail brush, lightly dab it in the grooves and cracks/seams.... Then I'll take a Q-tip and dab away at the excess paint, allowing only a small shadow to remain...
Sound right???
