Friends,

There was a discusion on Dynamat and equivalents, and someone mentioned
using foam as an insulator. I like this idea, and want to get your opinion
on the following:

1. Which foam to use? I know HomeDepot carries "Great Stuff" expanding foam.
Is this good to use.

2. Should I worry about moisture build up?

3. Would this create or acceralate rust?

I was not planning on doing this to the doors due to the moving parts
relating to windows and locks, but I would like to use this in the rear
quarter panels and trunk.

Thanks as always for your ideas/comments.
