Nice job with both applications! and you will feel/hear a difference.
I also used the Peal and Seal after searching/reading many many threads here on FABO mainly due to cost and availability.
Heres my original prior to application:

19 Again- did you use chrome duct tape or Peal and Seal with asphalt/tar backing?
That thing is smoother than a babys butt!
I also topped off with a Sound Deadener and mass backing on carpet. Overkill? maybe... but she sure is cool and quiet.
