Used it on a white HG kit for panel lining and the brown Real Touch formula blends way smoother than I expected, no harsh lines even when I slipped up. Takes a bit to dry but once it sets, wiping with a cotton swab cleans it off perfectly for that shaded, dirty look.
The blotting tip on this marker is great—it smears the ink into a soft, weathered finish that looks like real panel shading. Works perfectly for brown lining on white kits, and the color depth is just right for a subtle filter over decals.
