Heat/Sound Deadening Plan - Opinions?

[72malibu]

For the floor/rearwall I'm looking at the Flatline pre-cut butyl/aluminum foil kits (floor, wall), plus a layer of Siless Liner (closed cell foam), plus a layer of double-sided aluminum foil/cotton jute, then ACC mass-backed carpet.

For the roof I'm looking at Flatline pre-cut kit, plus a layer of Siless Liner, then the USA-1 Industries vinyl wrapped ABS plastic headliner.

For the firewall I'm looking at the jute/board OEM-style pad.

I'm planning to roll/brush 1-2 coats of Eastwoods rust encapsulator on the firewall and floor first. They are in good shape now.

I'm also planning to add some seam sealer where the kick panel sheet metal meets the floor.

Any advice?

No advice here , sounds like you got it under control .

don't discount the doors. a TON of noise and heat/cold is transmitted thru the hollow doors. sound deadener on the backside of the door skin as well as under the door panel will do wonders to help quieten it down & help some with thermal insulation.

2nd on the doors being a large noise source. Replace all the rubber and glass channels.

Otherwise looks like a good plan.
