All of the above is why I used Wurth sound-deadening sheets. Easy, clean, not smelly.

4 sheets do the tops, bottoms and the bells, leaving 2 sheets for flanges and sides if required. They are grey in colour but can be painted.

PS I couldn't get a picture of my treated horns attached to this post via 'Manage Attachments' but here they are in another post.
