I've been painting something with tamiya ts-29 from a can. I've painted other parts, and they come out fine, but this one piece always has a blotchy appearance, no matter how many coats I apply. I'm a complete novice, but I'm doing as every tutorial advises:. Mid 40s humidity, low 70s temp, base tamiya fine primer, a couple of mist coats of color, then a heavier coat, then heavy coat. The other pieces seem fine, but this one is always the same blotchy mess. Any ideas what I'm doing wrong? I did my best to capture in a pic
