Good Stuff
It does exactly what it is supposed to do. Only issue is that once opened, it does not last for future use. The tube cap is not air tight, so what remains in the tube after opening degrades and over time becomes unsuable.

It Works
Used to repair a porcelain English egg coddler by reattaching the top ring. Seems to have made a good seal and is holding up to emersion into simmering water. So, worked as advertised and allowed us to continue to enjoy coddled eggs from a keepsake from our three years in England. Good product that does what the maker says it will do.

I have been using this sealant for various applications and it works great. It does not appear to mold in a shower like many other sealants. I would highly recommend this RTV for any sealant application where you would otherwise just use a caulk.

Worked fine in my fridge
I used this to seal and protect wire nut connections in my fridge when I replaced thermistors. It worked well. This sealant is specifically recommended by GE service manual.
