geoff:
I agree polyiso is the way to go on new homes and any other place you want to reduce energy use. How did you insulate the Volvo, did you take out all the inside panels and spray? At menards they have inexpensive foam guns, but not sure where to get the polyiso. What do you use to foam and where to buy?
Thanks

PS I have to do this myself don't have any "ladies" to help me.
