Comments about System Three System Three Surf Board Resin:
Of course System Three SB-112 is a great product and in my case it is the only epoxy resin that is compatible with polyester resin when polyester is to be used over an epoxy repaired area.
The real story here though is Jamestown Dist.I have been a Jamestown customer for decades and I have never been disappointed with any product I purchased from them.
