Working with a buddy on a 72 GTO installing Vintage Air. It has been a long tome since I worked on these cars and I need some help. The install of the A/C is easy but I have some questions about insulation.

Everyone says use Dynamat and now there appears to be yet another product "Dynaliner" that Dynamat says goes OVER their Dynamat Product.

Does anyone have experience with these products? The main issue is heat insulation: this entire inquiry is driven by the A/C installation. The "Dyna" products are EXPENSIVE when purchased in the precut version (only Dynamat comes precut to fit the floor). It appears to be much more reasonable when purchased in bulk. Dynaliner apparently comes only in rolls.

Any info on the heat insulation results, comments on using Dynamat and Dynaliner together and sources for these materials in rolls / bulk would be greatly appreciated.
