3.
Bend the masking tape along the outer panel surface towards the door making sure the tape extends further inside the panel corner. And then place another masking tape to fix the position.
4.
Mask the whole door.
Reverse Masking:
Round up the masking paper to create a soft edge corner so that paint mist is applied thinly towards the end of line.
Use masking paper for the flat surface, and masking tape for the corners.
There are two reverse masking methods. One is to use a masking tape and another is to use a masking paper.

NOTE: Painting the way to the separation line defeats the purpose of reverse masking. Consider the size of repair area and apply masking with an ample margin.
Tunnel Masking

When giving a gradation paint to a pillar or similar parts, lift the masking paper from the repair part to create a tunnel-like space so that ending line of the paint becomes fuzzy resulting in smooth color gradation of the repair part to the original colored part. In some cases, the masking is lifted at two or three stages based on the cycles of the gradation paint
