I recapped my twin reverb re-issue several months ago with F&Ts and not long after one of the capacitors snapped a leg right at the body of the cap. I chalked it up to a bad capacitor and replaced it. Now that capacitor has snapped again. I did not “re-goop” them to hold them still so I’m assuming it’s vibrating as I play and has metal fatigue? What is the best silicone like material to use for this purpose?

GE Type II RTV Silicone Sealant.
Most RTV silicones exude acetic acid as part of the cure process; that acid (the strong vinegar smell) can corrode copper and tin. GE Type I RTV does contain acid.
But GE Type II does not.
Apply a small blob to the barrel of the cap to hold it snugly.

Be sure you allow enough lead on each side of the new cap to allow expansion, contraction as the amp heats and cools. I've seen this happen on amps where the tech who replaced the caps made the lead too taut and it eventually snapped. I try to put a gentle 90 degree curve to the bends and fold them under the board. (I completely remove the cap boards when I recap.)

In this case.....a bit of slack is a good thing.
