As you can see the cover for the JDM clusters was scratched and covered with scuff marks
After hours of sanding with high grit sand paper (1500 & 2000) and finish it by polishing with MEGUIAR PlastX. This is the result, pretty happy with it.
1. Sand it IN water, u will get a better finish.
2. Sand in different direction for different grit of paper. eg 1500 grit vertical, 2000 grit horizontal.
So that u will know if u managed to sand away the previous layer.
3. Keep buffing using the PlastX or similar product. Do a small area at a time.
