Can Lei Ling rear wheel liner be fitted with sound insulation cotton? Where can I buy it?

Lei Ling rear wheel lining can be soundproofed. You can buy it on a treasure or in a local car stereo refit shop, because when the stereo shop changes the door horn, you must stick anti-vibration, sound insulation and sound absorption materials on the door, and there will be sound insulation items.

Refer to the construction picture:

First, put a damping plate on the wheel arc.

Stick a layer of white sound-absorbing cotton on the curved mud cover of the wheel.
