Figure Step
1. Polish the damaged parts of the paint to re-
move the surface rust or other roughness.
2. Clean the target parts using a rag with
water or 97% alcohol to clean the dust and
dirty.
3. Spray the parts with base material exposed
with zinc primer (or other local primers with
the same function) for protection after drying
of the surface. The paints should cover the re-
vealed primer completely
4. Paint the scratched parts by banister brush
when the primer is dry, and make sure the
painting is as uniform as possible
