Hi! I am planning to repair some soft spots in the deck by injecting foam in between the layers. I think that this is the best method that does not add extra weight to the hull. Have others experience with this? I am thinking of using Urethane pour foam and use a syringe to inject it in between the layers, with additional holes, through which the extra foam can escape. If people know a good method and a good product, please let me know! G.
