Yep, sure does. I used it to insulate my livewell/beverage cooler and it worked great!

Not sure how much to do the outer areas. Just done my sf and make sure you have every thing ready and mix it well then pour fast. You don't have much time once mixed


To meet us coast guard flotation requirements I think they require the 4lb density or less but not sure on all the floatation requirements. Maybe some one on here knows more about the requirements.

Wow! Glad I checked back here I was planning on using 4LB to replace the box stringer foam. I guess 8 gallons isn't so bad as I took 6 large contractor size bags of nasty old wet foam out of the stringers. The temperature you use the stuff at makes a big difference in the volume / density for sure. The hotter it is the faster you better go. The stuff starts growing as soon as you start stirring it and mixing it.
