My little Mazda 3 suffers a bit from road noise, especially at the rear, so I was thinking of getting some Silent Coat and laying it in the boot floor, under the rear seat and over the rear wheel arches. About £80 worth should cover it all. Has anyone tried doing this sort of thing?
I'd turn the radio up to be honest.
Fair enough crikey, but the mrs doesn't like Pantera that much.
Get a new Mrs then
How much for the old one?
I did the floor of my VW Multivan while the carpets were all out. Made a massive difference.
Would have thought the boot floor would make a decent difference.
Better if you could do it all though.
Flashing tape from wickes does the same job far cheaper though.
Thanks Neal, I've heard that bitumen based stuff can get pretty smelly in hot weather. Is that what you used?
Supposedly. Although as I understand it, the best place to put it is on the big panels, like doors and roof. Most of the noise is caused by the large thin panels resonating, so you need to damp those down.
I heard of Dynamat being used - thick sticky backed rubber.
Try self adhesive silver foil backed flashing, cut it to size and shape it round awkward areas, a large 10m roll will be less than £30 and works just as good if you double layer it. When i stripped my Mk2 Golf back to a bare shell i removed all the bitumen sound deadening and replaced it with this type.
Check ebay for it.
Thanks Neal, I've heard that bitumen based stuff can get pretty smelly in hot weather. Is that what you used?
That's what I used yes.
No problem with any smells over the last three summers since it was done.
As mentioned above, I also did the doors and the side panels under the windows.
All four wheel arches and cab floor area.
It's like a limo now. You can barely tell it's running 😀
Me and the old man did his 110 made a big difference... Was thick black sticky backed stuff.
Really heavy though.
I had to take my boot carpet out and it was loud as hell.
Didn't put it back. 😈
Flashing tape is ok, but you tend to need to use a few layers for the equivalent effect of Dynamat/Silent Coat, etc.
You could get a couple of the starter packs, that's what I did (but never ended up using them).
There is some stuff online that's cheaper and beter than dynamat, apparently, if you look hard enough.
Wheel arches make a big difference, well worth doing in my experience
My MR2 is Dynamatted throughout, but that's mainly to stop sound escaping from the mahoosive install... 😈
Its a great project with a noticable result at the end - give it a go!
I used the bitumen stuff, if I did it again I would dig deep and go for Dynamat (or the cheaper alternative stuff if you can find it).
Just use carpet underlay, it's cheaper.
It's on my list. I found enough to do 2 cars almost, for £70 on a big roll. I love quietness in cars.
Why is the car noisy? Dodgy exhaust? Worn bushes? Cheap tyres? Knackered door seals? Not quite the sort of car to be noisy is it?
I think it might be the cheap Toyos on the rear. The car is only 4 years old and everything is tight, no rattles etc. It's not exactly a major issue or owt, but as its easy to do and relatively cheap I thought I'd give it a go.
What did you get Molgrips?
Have a look at the Car Audio direct web site they have a good range.
Did the doors in my Transporter prior to a new speakers , good stuff.
I used flashband on other areas, Used silver foil tape around the perimeter as the Adhesive can loose the bond when the car has been in hot weather.
iv used a layer of flashing tape toped with a layer of brownbread/dynamatt to stop the audio rattles/vibrations
