I have read mixed reviews about the Peel and Seal stuff at Lowe's... Sound deadening material is stupid expensive for what it is. I scored a great deal on the stuff I bought years ago and still have today. I am praying I have enough to do the Impala with... If not, off to Lowes to see what they have. Don't pay a shop to do the job... I made that mistake a long time ago and I still kick my own ass today for it...
