The trick with lining bolt holes with epoxy is to drill them out well oversize first, then fill them with thickened epoxy, then drill them out to correct size. That leaves a cylinder of epoxy lining the hole.
I didn't use epoxy. I just slathered the edges of the holes with plenty of thinned TB2 and plan to use paintable non-silicone window caulk to seal around the bolts and holes when I marry the floor to the frame.
