This is me, picking up my freshly repainted 914 from PMB Performance.
Now that it's home, it's time to start putting things back together. I'm looking for sound deadening solutions for the floor and interior back panel. I'm planning on keeping the interior back panel, but figured this would be a good time to enhance it with some sound deadening capability. My searches haven't been very successful. I'd appreciate it you guys could offer some advice or point me to previous threads on the subject. |

I know people will scream about the dangers of undercoating, and they are probably right, but one my 914s has what appears to be a rubberize coating sprayed under the entire chassis (and i believe inside the doors as well) and the difference between this car and every other 914 I have been in (which is a pretty large number) is very noticeable. Riding in it the car feels much more solid, quiet, much like 911s i have driven.
I can't imagine anyone would want to add a rubberized coating on a restoration, but thought i would add feedback from a car that has it. I would really like to hear feedback on, or experience, a car that has had the lizardskin product applied to the entire chassis and see how it compares as it sounds like a safer way to achieve a similar result. |

I would really like to hear feedback on, or experience, a car that has had the lizardskin product applied to the entire chassis and see how it compares as it sounds like a safer way to achieve a similar result. I have a '72 Pantera I built for street/track use (roll cage, etc.). I wanted to civilize the car while minimizing weight, so I applied both a Lizard skin sound control coating AND a Lizard skin heat barrier coating to the entire interior of the car while it was apart. I haven't weighed it, but I estimate it added less than 10 lbs. to the car. No extra Dynamat, etc. The Lizard Skin coatings work really well. The car sounds solid, no "tin can" feel at all. And with the windows up, even the engine noise isn't bad. I was expecting a lot worse: it has a 438" solid roller stroker Ford V8 (660+ dyno HP)exhausting thru a single big Magnaflow straight thru muffler (4" ID, IIRC) designed for turbo diesel trucks. So I can recommend the Lizard Skin route for sound control, particularly if you want to minimize weight (it also doesn't add any appreciable bulk under carpeting, either). The only downside is the application has to be done while the car interior is removed. Jack |
