Fellows make sure if you plug any holes in the floor boards that you fill the epoxy all the way through and spread some epoxy around so it will not come loose from vibration down the road. If you were to countersink a hole of 1/16" then the epoxy would not come loose. Ideally both sides. I have used it at work and have had it come loose after a few months without counter sinking. Marine Tex is much stronger and a little more pricy than JB. but has 46,000 PSI.
