[C320-list] Replacing engine sound insulation

[Steve Martin]

We replaced the sound insulation in #754 this past winter, using a kit from Defender.  https://www.defender.com/product.jsp?id=96141. Replacing the insulation in the fore and aft covers took two kits.  The process is pretty straightforward, with the most difficult part being working back to a clean-ish base.  After experimenting with different solvents to remove the old adhesive, it seemed that the best solution was spray Goof Off.  Although only one season in, we're quite pleased.
