Dynamat is quite expensive, as mentioned. I am going to try the Peel-N-Seal on my '66 K10 (BCKNBLK). I actuall kicked around the idea of having it sprayed with Herculiner, Rhino or Line-X, while I have the entire interior out to replace the floor boards, kick panels and inner rocker panels. I believe I will do the Peel-N-Seal instead. For the money and availability, I'll give it a trial run. Thanks for the information.
