Those searching for that annoying rattle... perhaps there's a solution, or not ?

Aparantly this will cause the same road noise through the CD player in the car allowing you to move freely around the cabin to source the noise

Rattle Buster

seen this mentioned on an airgun forum recently

if i had a rattle i would buy it in an instant

save having a mate lie in the boot while i drive over bumps

They interviewed the creator of the CD on the radio recently, and also played a couple of the tracks. Its not music, so must like listening to noise and various different waves (sine, square etc.), the tracks they played seemed effective.

What a weird idea. I like it, hope it works!
