Rotax 9 series engines - anti seize, thermal paste, nothing?

[danny_galaga]

Here you can debate the merits. Personally, I think Rotax should know what's good for their engines. They designed them. They have by now tens of thousands of hours of data on them.

To me the only thing to debate is WHICH thermal paste is a good alternative to the apparent hens teeth Rotax recommend.

I just use the stuff I use for electronics on heatsinks...works fine

Of course I forgot to mention we are talking about the spark plugs in case anyone is wondering 😄
