Want to add some sound deadening to my Corrado when i put the boot install in, and will probably do the front doors at teh same time. Was looking at teh second skin stuff but im jiggered if i know what i want :shake: ... Do iwant sludge or spectrum or damplifier...... I know the difference between the mats and the liquid / slurry so odviously the mats will take longer to install.... But whats the actual performance difference. Will be coating the boot floor, rear wings and rear panel wit hit in the boot plus inside of both doors ( which are large..)

Any advice? Maybe a pros and cons for sound deadening newbies as a sticky would be useful??

Thanks,
Mark

after getting my hand on some of the dynamat extreme copy that seccond skin can do i can say it's nowhere near as good the sheets are way too thin way too light and not as sticky i can't see them being any good, to get the same effect you will need much more making it much more expensive than dynamat.... get dynamat extreme and be done much sooner and cheaper in the long run.

Did you get the Damplifier, or the Damplifier Pro?

They are not a copy and the thickness and weight are not an indication to its performance. The adhesion (or apparent lack of) is designed such that you can re-position the sheet should you require when installing. Once in position the sheet becomes stuck fast over a short period of time, this is not something you would notice without continually checking the installation.

Having used damplifier pro, I'm very confident that it's every bit as good as dynamat extreme.. funnily enough, www.sounddeadenershowdown.com agrees with me too ;)

Highest Quality
Second Skin's products live up to their "Over Engineered to Over Perform" motto. They are clearly a higher quality alternative to Dynamat Xtreme - designed for greater heat tolerance, with higher quality materials.

If quality is your most important requirement, Second Skin Damplifier or Damplifier Pro are the obvious choices. Dynamat Xtreme is close, but being more expensive and not as good isn't a winning combination. I congradulate Second Skin Audio for their obvious dedication to providing the best product possible.

Having put some of the stuff in Mark's car, I completely agree. It's certainly at least as good as Dynamat Xtreme IMO. I've not bought any and this is just my opinion. This stuff works. In fact I've been extremely impressed with all of the Second Skin range :)

Yes, please be careeful with comparisons

Damplifier (sold in small packs) is the entry level product
Damplifier Pro (sold in large packs) is the closer to Xtreme

X3... Also a vote for Damplifier Pro being right on a level with Dyn Extreme for performance, but haven't stacked up how they compare per m/2 on price...

Damplifier pro works out at nearly £40 per m sq by my calculation. Don't know about dynamat extreme like as CAD don't sell it no more.

Dynamat Xtreme is £24.99 for a standard pack therefore to compare with your sums that would place it at around £62 per m sq - or £52 in their biggest bulk pack.

(Damplifier Pro drops to £35 per m sq in the bulk pack, and £32 if you include the forum user discount)

This is all very useful stuff guys, but any advice on which one isa actually best to use.... Not looking ot use 3 or 4 different products, and its not going to be a competition standard car, just want to improve the sound and reduce exterior noise.

Thanks,
Mark

extreme if youre getting it or damplifie pro both seem to be very good, work out how much you can get and for what price and see whats best for you. youd be hard pushed to beat the price on the second skin though!!! ;)

If you're just after one general-purpose product, the Damplifier Pro would probably be your best bet :)

Based on Mikes prices, the Damplifier Pro looks very attractive... Its real easy to work with, but wouldn't fancy shifting it around once its stuck and been on for more than 15 seconds-odd...

Not a problem if you lay it right the first time though!

Definitely worth the price, just make sure you bag a roller aswell, the metal foil doesn't show your hands any love...

Mark,

The best solution is to use a combination of quality matting like Damplifier Pro and liquid such as Spectrum or Sludge. The Damplifier Pro can be used on all those easy to reach areas to cover the majority of the door and floor areas and kill those annoying panel rattles. The liquid can then be used in combo, both to cover those hard to reach areas and also to double up coverage on areas that need it most.

Spectrum is thinner and can be applied by spray or brush and in multiple coats, where as Sludge is much thicker and can be "gunked" on in larger quantities. Which one you choopose is really just a matter of application, however in this scenario i would suggest the lighter Spectrum liquid.

If budget is tight, just go for as much Damplifier Pro as you can and apply it to the doors and front floor pan, the liquids can come later to finish the job :)

Me and Switch were doing the C4s doors + boot with Pro yesterday. He'll upload a "knock-test" video later, but with just a few pieces in the doors the difference was black and white. My back doors are made by Citroen, and my front doors by Bentley

Whilst we're on the subject, how would MotorMat/Sludge fair being pt directy onto the exhaust? Only I'm getting hell and all reverb from it inside the boot :(

I just did 2 layers of Dampifier Pro in my 1988 CRX this stuff sticks way way better than dynamat extreme!!!!!! plus it was a whole lot thinner and easier to install that the other namebrands

When comparing mats, don't forget to compare thickness and mass. When comparing identical compounds, damping effectiveness increases in a straight line with thickness until a point of diminishing returns is reached - almost always at a thickness greater than on layer of any of these products.

The ideal solution is to use both. Layers of mat covered with layers of liquid. 2mm of each will damp almost anything. The two product types are effective over different frequency ranges and have different viscosities.

That's twice the work and expense, so it will not be most peoples choice. To choose between mat and liquid, you need to consider your work environment. Liquid will take more time. If you spray or brush, you will need to make several applications with drying time in between. If you trowel on a paste, you can do the full application at once, but the drying time will be close to the sum of sprayed layers need to achieve the same thickness.

Generally, if you can take the vehicle out of service for several days, have a garage and ideally a compressor and are able to strip the car completely, liquids are great. If you work outside, or need the car for daily use, mats will be faster and easier to deal with.

I make it out at £38 for the bulk kit and £35 for the bulk kit with discount :confused:

Am i working it out right?

36sq/ft = 3.34sq/m

Without discount

£129.99/3.34 = £38.92m/sq

With discount

£129.99/100*10 = £12.99

£129.99-£12.99=£117

£117/3.34= £35.03m/sq
