Karl,
This is West System Epoxy so if you seat the beams with Six10 they will be glued down as a permanent bond. This is not a sealant so if you try to remove the beam you will be ripping gelcoat and fiberglass. Although not desired I'm going assume that there is some flexing going on at the beam attachment. I did not look at the boat you have if it is mention in your profile. If the beam is bonded to hull and there is flexing something will give and most likely it will not be the beam or the Six10. On my G-Cat I have a very secure beam to hull attachments, bolt through, and I've had beams split at the drill holes and glass split in very extreme conditions under heavy seas, wind, and weight.

My question would be what is the factor or thing that you are trying to achieve at the beam connection by using the Six10?
