I asked this question in the Arcade-Projects forums since this was for my Candy Cab monitor, but I figured I'd post it here on KLOV as well since it a pretty general question about using epoxy to reinforce a flyback.
----------------------
Was taking off my flyback in order to clean the infamous "Black Goo" that was everywhere.

In doing so, the brittle plastic support snapped off on the top. I'm inclined to think I should just leave it off and just put some epoxy there to prevent cracking, etc since these fly backs are obsolete.

Any recommendations on where to buy, what brand, etc. I'm near both Home Dept and Lowes, but willing to wait for any Amazon shipments too. No rush.

[Edit: Just bought this Epoxy from Amazon]

Lastly, I could always super glue it back on, then surround it with Epoxy. In the last pic below I have it snugly in place, unglued. Not sure what would be best.

Also, there was not a screw in the post before I removed it, so don't think it provided my support anyway. So I'm leaning towards leaving it off and using the epoxy.

Thoughts?

Just leave it off and put a dab of RTV silicone over the hole.

That support doesn't look like it served any electrical purpose, and was probably just a vent from when it was manufactured. As long as the potting of the main body isn't compromised or cracked, you probably don't even need to patch the hole. The plastic case of the flyback doesn't really provide much insulation. It's just a container to hold the potting when it's poured in. The potting is what does the work.
 
Hey @DeLuSioNaL29.... another forum member turned me onto this a couple weeks ago. Paint several coats over the offending area if you want some peace of mind. It's designed specifically for keeping high voltages where they belong. It can sometimes be used to stop corona leakage through cracks in unavailable flybacks.

If you opt to use RTV instead, you might do some research to find an RTV that has a high enough dielectric strength to do the job you expect it to do.

EDIT:
As far as epoxies go, JB Weld isn't rated as a dielectric compound... one would need to use one specifically designed for that purpose such as RS-2242 or similar.

You could look at it in the dark or use a grounded screw driver as a "lightning rod" to see if it shows any signs of discharge at the site of the break... that might be enough to decide not to do anything. YMMV

Ended up going with a light coat of epoxy after popping the piece back on. I wanted it to look fairly original since it worked fine prior to the epoxying and the potting was undisturbed. The piece that snapped off fit back in snugly. Then I added Gorilla brand, which is rated up to 180 degrees, so I'm not worried.

There were also some VERY faint hairline cracks along the body of the plastic housing. Nothing was cracked all the way through, but to prolong any future damage, I gave a light coat of epoxy with a small water color paintbrush. (I sanded the plastic gently beforehand of course to help the epoxy adhere.)

Came out great!
