My neighbor tried something similar and it looked great for about two months before it started browning out in patches. I'd give it a full season before calling it a real fix.

Yeah that mayo tip is gold. I'd add this: if you're doing a second coat and it feels a little stiff, dip your knife in water before you scoop. Just a quick wet, don't soak the mud. It gives you that little extra slip so you aren't pulling chunks. Also for topping compound I like it just a touch wetter than mayo, almost like a thick ranch dressing. Makes sanding way easier the next day.

Right, so @jake_torres68 basically hit the nail on the head. A retired bank manager handling a property line dispute sounds wild but honestly probably works because they're used to negotiating down to the last dollar. My case was super specific with the fence line because one neighbor had been paying for the land for like 15 years before the fence even went up. The mediator just sat there and let us argue for 45 minutes before she literally drew a line on a napkin and said "split it 50/50 or go to court." We all looked at each other and took it. No lawyer could have gotten that done faster.

Yeah because nothing beats paying extra for a label that falls off after two washes.

Depends how much time you wanna waste over $4.
