I should be able to easily finish up the welding and grinding on the passenger floor pan tomorrow. I bought a can of brushable seam sealer and a quart of POR-15 to paint the entire floor with. My question is what types of sound deadener you guys have used and how do you like them? I plan on using one of the full floor mats from LMC with juke backing but would really like to put something under the seat, in the doors and on the roof to get rid of some of the empty tin can sound.

 

Hey Larry,

I guess I'll be the first to reply....depends on how long I type. Anytime someone ask about sound deadening I wish I could convince them to at least read this website. https://www.sounddeadenershowdown.com/ The guy is really good and knowledgeable. I've fallen into the trap of spending a ton covering every square inch of interior with Dynamat. Nothing wrong with that but it's completely unnecessary. That website will explain in detail all of it. I'm not saying you have to buy his products but after reading how to do it correctly you can maybe save some cash and also end up with a much better result.

Good luck,
Wayne

 

Wayne:
I look forward to reading that article when I get a chance...too busy watching the burgers!
But I suspect it will verify what I have experienced from three restorations and that is, just covering a portion of exposed metal with a sound deadener will have a significant effect. Once you stop the metal from vibrating or drumming, that's about all you need.

 

I've seen some people use dynamat with good results. There's also other brands that do the same thing. There's also spray in types which are good as well. I like that they can protect your floor and look nice if you don't want carpet or rubber mat.

 

It reminds me of some high school science projects involving water tanks with a wave generator at one end. We could watch the waves being generated by looking at their shadows on the bottom. By playing with cross blocks with different sized openings we could cause the waves to amplify each other or nearly cancel each other out.
