Hot take: my old boss's "close enough" rule finally made sense at the shop last month
Had a quick talk with a guy who's been pulling dents for 25 years at a shop over in Mesa, and he said something that stuck. He told me he stops block sanding the second his hand feels flat across the filler, even if the guide coat says otherwise. I used to chase every low spot with a rattle can until my arm fell off. Last month I tried his way on a dented Silverado bed side and the primer sprayed clean on the first go, no pigtails, no redo. What's the one little rule you picked up from someone older that you still use?
