Using AEROSOL FOAM for Insulation

[maldo]

Munster is getting close... ANY moisture that comes in contact with the "Great Stuff" open cell expanding foam will wick right into it. I have seen the exact same issues with this stuff Derek mentioned. Do NOT use it as a sound deadener... Condensation is another factor that compounds the problem. Once this stuff gets wet it will never dry out.
Do not compare the proper use of this stuff in a house to the environment it has to endure in a car. There is no comparison...
Take it from me, this is not the stuff you want use. Spend a little more money and do the job right. You'll be better off in the long haul.

Hi again i was not going to go crazy with the stuff (an I understand certain panels need to have water drain through it)
was not really planning on filling up every gap (LOL) but to use it more to fill in some of the hollow spots in the body where water does not pass thought
My main goal of the post was to see if anyone and used it in a automotive application.
