The 2013 Sonata trunk before adding Second Skin Damplifier Pro. Look at that bare metal screaming for butyl!

She ain't afraid of no butyl!!! Sydnee rolling Damplifier Pro on her trunk vehicle like a pro.

Next up, time to add sound deadener to the rear deck on top and bottom. Sydnee also used Luxury Liner Pro to the trunk wheel wells and floor.

Next up is the floor. She's got the Sonata fully disassembled fully and is throwing down that Damplifier Pro sound deadener

When your goal is vault-like silence in your vehicle, Luxury Liner Pro mass loaded vinyl across the entire floor is the next step to get you there.

The 2013 Sonata doors took about 6 sq ft each on the outer and inner skins.

Pro Tip from Jeffrey H: When installing door speakers use Damplifier Butyl Tape to keep wires from slapping around. Also use it on the back side of the speaker mount to ensure your mount is solid and won't vibrate.

When you are wanting to max out your results, you got to hit up those flimsy door panels too. Sydnee reinforced her Sonata's door panels with Damplifier Pro and later with OverKill closed cell foam.

Back to factory look from the outside. The sound deadening secrets hidden beneath the panel.

Inside, outside, and upside down...Damplifier Pro is the one trusted to bond for life. Great work on your roof Sydnee!!

Fitting together like puzzle pieces. Time to add some extra insulation to the roof with Mega Zorbe

After all of that work sound deadening the roof, Sydnee's Sonata goes right back together. Amazing work Sydnee!!!

Sydnee has her Sonata looking fresh and clean while she rolls down the road in tomb like silence. #SecondSkinForTheWin
