Floor tar repair/ restoration Options

[TonyA]

What does everyone use to repair floor tar sound deadening material. I have some popping up very little rust the cause of course. I am removing a small amount to good sound completely rust free areas and want to restore that to like new appearance. Any suggestions?

Just curious....those interiors look beautiful.

Why not dampen the firewall (inside behind the backpad) the the foreward wheel wells and front bulkhead? Those are two next largest resonant metal panels.

With regard to "sound absorbtion" and "resonance", two different things.

I've worked on a couple of projects in my career where both were concerns.

Sound absorbtion uses different ways to "disrupt" the sound waves.

Sound resonance damping is what you guys are talking about. It's the actual transfer of the sound energy to the metal panels. Like a shock absorber on a car.

Sound absorbtion is a sort of vodoo science...really cool stuff almost like quantum physics applied.

Curious about the comaprison since the only differnece I see from the layered product is the layered composition and buytl....other than that....it's the same stuff in layers of foil with sticky Avery crap on the backside.
