    Hey guys, I'm new to this forum. I picked up a horrible rotten mess recently that I just finished cleaning up. It's a 6'6 polyurethane fish with major rot around the fin boxes. After deglassing the fin boxes practically fell out. I removed all the rotten foam away from the boxes and rails but now am left with less material than I expected. I'm considering all options: Microbaloons, Qcell, 4 lb polyurethane pour foam.

    What are the pros and cons of each. I obviously need something strong enough for fins.
    Thanks guys!!

    That is the perfect application of pour foam. 4 lb density if fine. I've used it filling in huge voids to replace fin boxes. You can also use a mixture of resin and microballons to fill the voids
