Default 2 Part Liquid Expanding Urethane Foam

Andy,

2LB density is the one I use:

http://www.uscomposites.com/foam.html

Not that expensive @ $20.50 for the kit and it produces about 2 cubic feet of foam. Seems pretty close to what Giant Leap and others are selling.

I used it to fill the fin can on the 4" dia. rocket below between the 54mm motor mount and the six fins. Two small pours of a couple of ounces filled all that volume to the rear centering ring.
