Pacer formula 56 is the best in my opinion. This used to be called RC56. It looks like Elmer’s white glue but dries crystal clear. Only down side is it takes time to dry.....like old school glue. It wipes clean with a water dampened paper towel with no resulting damage. If this was not available I would use (and have) epoxy. CA is just to unpredictable for me. I usually end up with that white fogging that can’t be removed.
