High Heat Gasket Cement vs Heat Sink Grease - which is better?

I have been using a stove to fiberglass gasket cement to cinch up any gaps in by brass hot end resistor block, and it works pretty well. I've never had one fail, but was wondering if using a heat sink grease would be better? If a resistor did fail, it would probably be pretty hard to remove if it has been cemented in place. With heat sink grease, it would be easier.

Any thoughts?

Should be a little easier, but heatsink compound does tend to solidify over time (As someone who has removed too many old pc heatsinks to count...).

And, our resistors are MUCH hotter than the temps most heatsink compound will normally see. I don't know how that will affect it in the long run.

That said, I'm using arctic silver on my resistor and thermistors, it seems great, my temp readings are perfect when compared to my multimeter. That said, I'm new to this so only time will tell how heatsink compound holds up in the long run.

Have you tried using high temp silicon?

you can buy it at most DIY places as they use it on kitchen stove flues.

just have a look on the info normally supports up to 300C

easily removed when you need to unlike thermel paste which dries out very fast at high temps.
