Sound deadener and Quarter panels

[Bighouse]

1969 Charger—I’m planning on applying the sound deadener to in inside of my quarters and a coat of paint before I install them

Whats everyone using to mimic the factory coating seen from the trunk?

and what are people using for modern application in the passenger compartment?

Thanks

Rick's Resto has the product that closely resembles the factory undercoating. The only
thing that I'll say is that I could never apply it the way the factory did. I had to put mine
in alot neater!
