  1. Jerry Skofield

    I have used SOS to repair my boats for three years now. Every year I usually have some damage and need a new bottom paint job done. Brian has used these products on my boat and every year they still look good. I have used other repair methods and they all have cracked or shown damage the next. I highly trust this product and I’m glad it has become available to the public. I can try to fix on my own now.

    Worked great. Good to have a thick epoxy putty in the arsenal. It cures super fast when heated.
