Removed Interior Floor Tar, Now What?

[FrictionTape]

During restoration, I removed all the "tar" covering the interior floorpan/footpans. Now that I am ready to spray the floor with epoxy, install sound deadening and then carpet, what's recommended to do with the floor before I do all this? Nothing? Re-tar it (is that a thing?)

 

Your feedback/insights are appreciated.

I'd recommend resealing the 4 floor plugs unless the sealer used looks to be in great shape. Other than that clean and ruff up the floor as per the primer instruction and go for it.

I put sound deadening back on street cars.  

 

It really helps, as does a jute layer under the carpet.

I vote no on adding any tar. If you coat the floor with truck bed liner it will cut the noise quite a bit  when combined with a mat product.

After new epoxy and seam sealing like SonofMarty noted, I used tinted Raptor liner and then Dynadeck. This thread has some good pics and mine is in their.

This is great, thank you!

There’s products that will work slightly better than truck bed liner for sound deadening. Spectrum is one I’ve used on other vehicles with good results and lizard skin is another.

Main drawback with using jute under the carpet:  if you either have a heater or windshield leak, or your A/C condensate drain hose gets plugged and the pan overflows, or you track a lot of water in on your feet when it's raining, jute will hold water like a sponge--for days or weeks.  Water = rust even with paint on the floorboards. 

 

Suggest using 7/16" "rebond" carpet padding--the kind that's "pet-proof" since that stuff has a waterproof barrier that's equally good for pet pee and water.  You can usually scrounge free pieces from a local carpet store--either by asking or a little dumpster diving.  Just get new stuff  😉.

Well, I've been wrong before...

does agree that a sprayed sound deadening would probably work better.

But was also assuming a proper seal and encapsulation, first, not just 'paint'.

Mike, the rust on my car's interior was a result of what you described. Well in addition to no longer having an AC unit I only painted the used used bedliner after I welded in new pans.Two reasons for this.My reasoning was that if I have heater core leak it will make the carpet wet and that is something I would notice much fater with no jute padding underneath.Secondly I wanted much less bulk to the pedal cluster area since its so small to begin with.

I'm in the exact same situation.  Is anyone using Resonix?  Seems to have a solid reputation, and they have test results vs other manufacturers (albeit not independent tests).
