Undercoating on the interior??

[jarred767]

My car's interior is currently torn apart (my water tank leaked roughly 20 gallons of water and I had to tear it apart, big operation, but it's taken care of and completely empty now)

I was recommended to maybe put an undercoating on the frame (on the inside) to reduce road noise and improve insulation.

Has anyone done this before, does it really help much? I'm guessing I'd need to tape off/cover any electrical wiring, but anything else I should be aware of if I go forward with it? Thanks all!

Check out Lizard Skin sound deadening. Last time I saw it, it was available in ~2 gallon container. It will seal the floor while reducing sound and heat.

That stuff looks cool and legit, probably more than what I'd be interested in as it would be just a quick project. I have to have my car back together by monday morning for a mobile job, so probably would need something that I can prep, apply, and dry within 24 hours or so. Maybe that's not even possible??

If you have a local NAPA Auto Parts they sell DynaTron Dyna Pro rubberized undercoating and sound deadener. That's the only thing I can think of on short notice.

That depends on which formula you use
They have one for heat and one for Structural Sound..
Better alternative to lizard skin would be Second skin audios firewall and spectrum/sludge
It doesn't have to be sprayed on like lizard skin..but can also be rolled or brushed on

These most likely won't be better then matting due to the lack of mass

My thing is
If you're main point is to simply coat it while gaining a lil heat and Structural(non airborne) deadening then go with the liquid stuff

If you're main focus is sound dampening and heat reduction then go with matting

SDS CLD matting for Structural Sound
Heat wave pro for heat control
CCF for a decoupler
MLV for air borne noise reduction

Dynamat it

Dynamat it

Dynamatt performs average considering the price per Sq ft
But its all in what OP is trying to accomplish
Looking to simply seal top of floorpans?
Looking for Structural Sound dampening? (CLD matting
Looking for heat barrier?
Looking for air borne noise reduction? (MLV)

PS tlthat canned rubber stuff usually peels off easisly
May be better off with herculiner or something(roll on bed liner)
But prep is always key to success

Thanks for the help guys, it was never a planned project, only happened because I needed to eliminate the water and figured since it was gutted.... I've got it all taped off and I'm gonna spray a couple cans of the 3M stuff on it (thanks for the suggestion Ebg18t), that sounds like the best/quickest option for my scenario to do right away before putting it all back together. Hopefully it sprays on well!
