Thinking of doing the floor and bulkhead in the Sierra to make it quieter, worth it?

 

Yes! do inside the doors to

 

Yep!!
Large areas of mine done, also under bonnet, in boot & floor panels, then double thickness of insulation. Cant stand noise.

 

best thing i ever did on my old defender. massive difference..

 

double post.... dunno how that happend

 

yes makes a big diffrence good if you are putting in a good sound system good at couting out road noise

 

there is a cheaper 1, think its called brown bread, same stuff.

 

roof felt would probably do the job.

 

you joke but the cheapest way of doing it is by using flashing tape, its 99% the same stuff but on a smaller roll.

 

who said i was joking.

 

Martins unit suddenly has a big leak he has to fix with flashing tape lol.

 

use aluminium or lead flashing for roofing if your not fussed about weight etc,
same stuff really, bitumen based and alot cheaper,
brown bread is cheaper than dynamat tho.
easier to apply and make fit to floors when warm so either have a hair dryer/ heat gun handy or leave near a radiator to get supple!
