If paint is still wet:
- Dilute the paint with some water, go over the lap marks and smudge the intensified area using a circular motion or criss-cross strokes.
If paint has dried:
- Use the leftover paint available or get a new tub of the same variant.
- Then, add paint onto areas A, B, C and D that are now lighter than the lap marks to make it even again.
