When you say the color was bleeding down her curl pattern with balayage, was that happening right away or more like weeks later when it started to fade? I ask because I've had clients where the freehand stuff looked great on day one but then the ends went brassy and the root shadow got muddy. With foils at the root, did you have to leave any out to avoid that harsh line where the highlight stops? Curious how tight you went with the weave too, like did you take bigger sections since 3C hides a lot?

Kill fee spelled out" is smart but honestly half up front already protects you.

Caulk has a limit and 3/8 inch is way past it. That gap will open back up the first time that tub flexes or the seasons change, and then you own it forever because your name is on the punch list. Here's the part nobody talks about: the GC is not really asking you to hide it, he's asking you to take the blame later. Once you caulk it, the paper trail says the framer was fine and the finisher screwed up. I've watched guys get called back two years later to fix cracks that were never their fault. Tell him you'll caulk a 1/16 gap all day, but 3/8 means somebody planes that stud or adds furring, and that is not a punch item, that's a redo.
