I've heard good things about Smith's CPES. Lower cost/oz than any other product. I've use an entire quart (2 pint kit) of it and have received good piece of mind as a result, but no quantifiable evidence of it's effectiveness. They make lofty claims which i don't mind testing on non-structural areas. As for proper structural repairs in load bearing areas...other's suggestions are probably safer.
