I am starting the restoration of the front bumper. It was bent with a lot of deep scratches.

After sanding with an 80 grid paper and getting the dings out, I spot all the issues.

Deep scratches require using a file.

Back to sanding

I have sanded from 80 to 2000 (80, 220, 400, 600, 800, 1000 and 2000)

This is before polishing.

Done.

Now protected with plastic food wrap to avoid anymore scratches.
