Once the race car bug hit the partner and I, it was an unmovable force. We were destined to take the 2100 Miata and lose every gram of weight possible.
On a late 2AM night, we decided to purchase some dry ice and remove the insulation in the trunk. To do this at home, wait until 2AM, drive to your 24 hour Safeway and purchase about 3-5 lbs of dry ice and a few bottles of isopropyl alcohol.
Come back to the garage and mix the dry ice and alcohol into a bucket. Next pour the mixture into the trunk and watch the sizzling.
Now grab your trusty hammer and screw driver / chisel and start knocking the sound deadening off. Eventually, it’ll all come off in chunks and you’ll have a clean trunk with probably less than half a pound of weight loss! Success!
