In this photo the epoxy has cured and I have removed the Duck brand UV resistant duct tape. It seals perfectly and is not affected by the curing resin.
TIP: Before applying the tape, wipe the surface clean with Acetone or a strong solvent that will remove any grease or wax. The tape will seal and stick better. Gorilla brand duct tape is about the most adhesive you will find and also works well for this type of job.
