Dear All,

 

Yesterday Ken Wilford recommended against using recycled cotton fiber
home insulation bats to soundproof to my 83.5 V'gon. He warned that the
insulation could absorb moisture that would be transferred to the
fiberboard panels and lead to warping. That all makes sense (and I
always values Ken's wise advice); but I would be curious to know if
anyone has tried that solution and kept moisture from getting to the
panels by renewing/replacing the plastic sheets that were (theoretically
anyway - I don't think I ever saw them on mine) originally glued to the
walls of the vehicle, behind the clip on panels. Is there also a risk of
moisture getting trapped in the insulation that would then lead to
rusting of the body itself, from the inside out?

 

Ken also informed me that rubberized "ice and water shield" used on
roofs is essentially the same product as the adhesive, rubber
soundproofing material sold on the internet. I have plenty of that lying
around after a roofing project on my house, and wonder if anyone has had
good luck installing it. How well does it stick? Do you have to warm it
up before applying? Does it really absorb road noise? Has anyone tried
applying more than one layer?

 

I am researching the archives; but any current thoughts would be much
appreciated. 

 

Also, does anyone have a link to Matthew Bulley's treatise on the
subject.

 

Finally, is there any difference between the white "Kool Patch" and the
black?

 

Many thanks.
