So after reading a lot of threads on Dynamat and the like, and having lots of free time where I can't drive my car.. Grr, I decided I really need to lay some down. The road noise in that car is insane. Did our cars not come with any deadener?!

SO, I'm trying to decided between RaamMat and Peel n Seal. I've heard good things on both, but a few concerns.. First, does it smell in warm temps? In the search, I read opposite things. Up here in North Idaho.. It can break 100 in the summer. Mind you, it doesn't do it often, but if the stuff can't take 100 degree outside temperatures, I won't want it.
Second, does Peel n Seal come loose? Again, alternate statements in search. T-top car here, no roof stuff... Well, maybe a little.

Thanks All.

 

peel and seal will NOT hold up to 100+ temperatures if the car sits outside. also it stinks, and doesnt deaden sound as well as dedicated mats. unless you're REALLY on a budget, get the real stuff. i just spent 240 bucks on one roll of raammat and 6 yards of the foam pad, at 14 sq ft per yard, and 3 cans of adhesive (he tossed one in free)

 

How good is that Lizard Skin stuff I saw in the Summit catalog the other day?

 

Mean just started a deadening project post thing. Check it out here for some ideas.

There was also a thread a few months back by some girl asking what kind of deadening to use. There was a lot of good info in there about various brands, etc.

What kind of noises are you worried about? Mat will only take care of the lower frequency stuff and help eliminate rattles. It won't do much to road noise compaired to a foam mat.

 

I'm looking PRIMARILY to kill the really loud road noise.. I've got a sub, but for some reason, my car just doesn't rattle THAT bad. With the exception of the liscense plate, there realyl aren't any. Might also be I listen at a normal level though..

So, peel and seal won't work for me then? Smelly + will melt off? Good I asked.

 

Peel and Seal doesn't smell bad at all. Atleast not that I've experienced. Then again I'd never let my car's interior get to 100+ temps either.

 

I thought it was asphalt based? Therefore it will smell but it will air out over time. How do you keep your interior under 100, especially during the summer? Park the car in a parking lot at the movies or something and come back 2-3 hours later and bake.

 

I don't take my car to the movies. I take it out for car shows and for cruising only when the weather is nice- even at those times the interior never sees 100+ degree temps.

 

Lucky...

 

Justin,
Forget the peel and seal junk; go with RAAMmat. I've used it on one of our Trans Am's and it's good stuff. Clean the floor with something like Purple Power, and make sure to wear latex/nitrile gloves, otherwise it will give you a bad chemical burn (as I found out).

I bought a whole roll of RAAMmat and still have half a roll left. With a single layer it damped the sound quite a bit, but I'll be laying down another layer on the firewall and seating area to get the noise down even more. It doesn't smell and sticks like crazy, so make sure you cut and fit it before you peel the backing off and press it on (hand pressure is all that's needed on a 70 degree day).

 

So you've tried Peel and Seal? If you would have you'd know that it too, "doesn't smell and sticks like crazy."

What do they say.. don't knock it till you try it!

How'd things work out Justin?

 

Well, it's all in.. I had a bit of a challenge.. Being 30 or lower here lately, I had to heat it up using a propane heater, but I learned: when hot, it's insanely sticky, and it doesn't smell.. It was hot enough to burn me a few times (luckily no permanent damage... ) and I never smelled anything.. If I did, I would have stopped right then..
That said, the car isn't done yet, so it hasn't even been turned on, no comments on the actual deadaning power.. Good news is, it isn't coming off, and there's no smell.

 

Good deal Justin, keep us updated!

 

I agree! Do keep us updated as to how it works out. I need to do my car... but when you have a four banger any extra weight sucks

 

At the current rate, which varies dramatically based on other things, it should be at least able to take for a spin in a week or two.. I'll try to let you know then...

Based on just how the panels sounded when I banged them and stuff, I don't think it will yet be a "quiet car." That said, I DO think it will be quieter... All in all, it's probably worth it. But, if you were expecting a truly quiet car, just from how the panels sound when I hit them, this MAY not be the stuff for you...

But then again, the car hasn't even been on, so I doubt this is an informed opinion either way.

 

Figured I'd throw up a progree picture to give an idea.. I also realized I have to die that amp board black..:S That grey looks really bad to me now..

 

Not all peel n seal is created equal, I got mine from Goeckers and it has a golf ball texture, is about 1/8in thick, doesn't smell and when heated with a heat gun was insanely sticky but I could NOT get it to run with the heat gun! I trust this stuff; now on the other hand we have the peel n seal sold at Lowes that is about 1/16in thick, is sticky cold or hot, and just doesn't look like something I would put in my car. I personally think that the people making peel n seal are making "insert name" mat, and that if you're smart about it you can save some dime and get a good product at the same time.

 

Not true. A lot of the better mats are butyl based (synthetic rubber type substance). ED makes a butyl and an asphalt mat as does dynamat, second skin, etc.

 

True Peel n Seal doesn't come in a butyl base (that I've ever seen), so this would only include the asphalt based deadening products. The Butyl based products are lighter and are said to work better, if I were deadening my Camaro (which I'm not) I would want butyl because of it's lighter weight, in my daily driver Prelude I wasn't worried about weight and used the asphalt based peel n seal.

 

Lighter by mass, yes. Lighter by area, generally not. Butyl mat is typically a good deal thicker than asphalt mat. It also won't melt/get runny in the heat like asphalt will. I'm deadening my bird but mat is far too much of a hassle. I'm going liquid instead

 

Since it's at the top, a quick update:

Nothing's changed...

That said, it goes for paint estimates and body work estimates next week, and the new engine (350 HO) I should have by saturday or thereabouts.. So it's coming together...

 

And to clarify... Mine was either Home Depot or Lowes, but mine had to be hot to stick too. I wouldn't call it an adhesive backed product, just when the stuff gets hot, it sticks to stuff.. Kinda dumb sounding, but until it's hot, it's just like a smooth glass, kind of.
