Hi all
Nice to see the post still running, ive removed all the bungs and waxolyed inside the door panels - i have had not had any problems yet
My advise is to remove the bungs completely i wouldnt bother with cleaning them and refitting. I also advise you to soundproof the inside of the doors (if your taking the panel off) and waxoly the areas left out especially the inner door seams and bottom edges, as this is where the dirt will collect.
Dont worry about wind noise - you wont hear a thing amongst the normal rattles and squeaks
Good luck and long live Jeremy Clarkson
