Allow Paint Layers to Accumulate

What happens here

After the initial preparation, allow the paint thinly spread on the bucket sides to dry completely. Continue using the same bucket for subsequent painting tasks. Each time, follow the same procedure: transfer excess paint, then spread the remaining thin layer around the interior. Over several days or uses, these layers will accumulate and bond together, forming a thick, peelable shell of dried paint.

Goal: Build up multiple layers of dry paint inside the bucket
