Post subject:  Sound deadener for Mini Roof
Can anyone tell me if they have used spray-on sound deadener on the inside of there Mini Roof? instead of the felty type stuff, that came with the Mini.

If the sound deadener works for underneath the car, wouldn't it work inside the car???

I used "Dynamat" on my roof. I don't see why under body deadener wouldn't work on the roof.

I'd probably go with the dynamat as i think the underbody sound deadner may be fumey .

I also used Dynamat on my roof. Although my car isn't on the road, I've noticed a remarkable difference in panel resonance, ie, when the doors are shut. There is now only a dull thud, compared to a tin like noise.

I have used a water based under body sealer under the roof before, Wurth SKS works well. Just DON'T use a bitumen based sealer as it will melt in the sun & stink!.

"Flapper"
Just did my wifes Cooper. As said above, bitumin will stink and go soft on a hot day, and will carry the heat in summer.

I went to a carpet place and they have the grey underlay stuff. (looks like grey composit type stuff) Wasn't expensive and fairly light. About 3/8" thick.
Stuck it in with contact glue. A little tricky.
It did make the two peice roof lining a little tight to fit, as the bows touch it.

Cheers Alex

Do not be tempted to fit the headliner without it.
It is like sitting inside a 44 gallon drum! As we found when we owned Barney (the PO had left it out during the rebuild...) :cry:

Dynamatt is good, so is flash tac from bunnings, heaps cheaper, my father in law once used brush on tar and pushed cardboard onto it, apparently it worked well.

Whats flash tac ? and is it really comparable to dynamat ?

People are always comparing flashtac to dynamat - similar but different stuff.
Main difference is the glue in it is about 1/10th the strength of dynamat - so in your roof it'll fall off. The aluminium is also much thicker, and the rubber / bitumen stuff a harder compound, making it harder to install to tight and curved surfaces.

I used stinger roadkill on my roof which is a similar concept to dynamat but a bit cheaper I think. Anyway huge difference in sound. Doesn't ring for ages anymore, sounds a lot more solid.

Now I need it on the doors :/

I used the original felt stuff. Lot lighter than dynamat.

Weight is always a consideration.......

If I listened to my doctor & went on a diet, well it would'nt be so much of a problem :cry:

Clarke Rubber sell a medium density foam with a sticky back. Lasted for years so far....

Don't forget you don't need a 100% coverage.

Cheers, Ian
