Put some of the herculiner in the trunk of a convertible I had stopped alot of noise but the odor from the stuff stayed in the car for almost a year and that is in a convertible with the windows down almost all the time.

Are you talking about like a thick rubber mat? Or something like a Rhino Liner?

Herculiner is a rolled on epoxy based bedliner similar to rhino liner

Great stuff for noise reduction and underbody protection from almost anything. Fourwheelers LOVE the stuff inside and out on our vehicles!

Downsides: Expensive. Very Permanent.

Herculiner is a thinner, weaker, cheaper d.i.y. version than professionally applied LineX or RhinoLiner.

Another effective d.i.y. alternative is Marhyde #4311 Professional Rubberized Paintable Undercoating. Also very tough stuff and even attractive. Nothing at all like the tar undercoating you generally think of.

Hi I just bought a 25 sq ft. Of fat mat which is basically a cheaper version of Dynamat. I'm going to experiment putting it under the rear dash and I was thinking to stick it to the back of my door panels cause they are original and falling apart a bit anyways and it could help to reduce road noise or just help the car sound more quiet in general. I would love to eventually line the whole floor with the stuff... but speaking of smells it kinda stinks!

I'm trying to cover up the sound of my FM exhaust.

Make sure whatever you cover the floorpan with, know that some areas will get pretty warm, so keep that in mind, especially if you don't want things to start getting stinky while you're out crusin'.

Nice car, split bumper '73's are hard to come by...great find! :D

fatmat smells like a fresh repaved road when it gets hot. its a pain to install and it didnt give me a definite noticable difference in my truck. at least i bought the 25 sq ft to try it out first. LOL

You are not going to notice much with only 25sq ft. I tried.

I use the dupont stuff they sell at autzone in the blue cans and aerosol cans.

Comes out pretty good, did both my wheel wells with it, and the floor inside the car as well. As with everything, be sure to have a fairly clean surface to apply it to (though to be honest I think it will adhere to everything).

how does that stuff dry? Does it harden at all? Or, stay gummy?

Mike, I think he's talking about the rubberized undercoating...it does harden up unlike the older tar substance that the factory used.

I'm hoping it does harden up a bit.
The last time I used a spray on aerosol undercoating, it never dried. Always was gummy and sticky. Hated it. I'd like a nice hard rubber surface... but cheap and easy is attractive...

This is the Dupont Truck bed liner from aerosol can, almost as hard as powdercoat, easy to touch up, nice semi gloss color, fills 40 grit scratches easily, surface must be clean, the rougher the finish the better the adhesion. Wheel wells are painted with it.

It hardens up like rock, and fast. Dry to the touch in 20 minutes here in the desert.

Used it on my cross member and other areas of the frame when I put my engine in. I think it's actually duplicolor, not dupont. :screwup:

I'm sorry about that, you are correct it's Duplicolor.

The Marhyde paintable rubberized 4311 also dries hard, but remains flexible. Nothing like the gummy, sticky tar of regular undercoating. I have tried the 'bedliner in a can' and wasn't impressed. Both dry looking the same and the Marhyde is actually more resilient and tougher imo.

I was at Autozone today and did not find Marhyde 4311. They had 4211 or something like that. I don't know anything about that stuff or what the difference is. It may just be it comes in a regular-sized smaller spray can now.

I like the Marhyde because it is easy to apply and touch up each fall and it dries fast (overnight). You can do multiple coats and build it pretty thick if you want to. Like anything else, dirt and oil will reduce it's adhesion, so prep well.
