1974 Chevy Stepside - Sound Off

He sprayed adhesive on the driver side of the seat pan and installed the Heat Absorber/Sound Barrier material.

With the handy wallpaper roller, he made sure the insulation stuck well.

Locating the seat brackets by feel, he cut holes in the appropriate places.

Applying the remaining seat pan Sound Damper Pads came next.

John sprayed the center section of the seat pan, the corresponding insulation material, and waited a beat to permit the glue to get tacky.

The trusty wallpaper roller proved invaluable yet again. However, J.B. commented he'd use a wider roller the next time.

From installing the driver-side insulation material, he learned that applying the glue to the seat-pan sheetmetal, then cutting around the passenger-side seatbelt, would allow ample time for the glue to get tacky.

Now a veteran with the spray can, J.B. applied the glue to the backside of the passenger-side seat pan insulation piece while standing.

He smoothed the material and cut a hole in same to accommodate the seat bracket, which permits bolting the bench seat to the floor on the passenger side.

To install the transmission tunnel insulation, John applied the Sound Damper Pads and sprayed the area with adhesive.

Once the material and the sheetmetal were tacky to the touch, the two surfaces were mated to each other with the roller.

The Sound Damper Pads were applied to the amply dried Rust-Oleum-treated toeboards.

With the supplied silver seam tape, John taped the seams together.

Utilizing tin snips, J.B. cut the Zinc-treated, 26-gauge sheetmetal panels, which would plug the holes in the toeboards.
