Anyone have any experience with removing and re-sealing this?
I haven't done that exactly, but i'd reach for loctite 567 for any sealing thread jobs.
As an apprentice I was shown how good itnis by putting some on a taper plug and threaded loosly (not even finger tight) into a pump which was then hydro tested with water to 6 bar. Not a single leak over the 1 be pressure hold.
These days I use it as at work on steam pipe threads, steam gasket faces, oil lines, autoclave lines. Temperatures at 180 degrees cel @ 8bar pressure. Vacuum at .03bar at 134c for the autoclaves. It's good stuff and holds up.
At home, I use it on every sump plug or oil filter cap. Just do it up only just tight enough to not come loose before next service. Never had a drop leak.
There is another variety which is yellow and dried hard. Not the best unless you envisage a more permanent seal. Just makes getting threads out painful. Not sure of its temperature stability.

Essential part of my weapons of war... E.g. Sealing plugs when I have cross drilled a block for sustained high rev use (2 and 4 mains). It's the sh**!
