I do always use 243, never had any issues, BUT under some conditions : I apply it on "not so degreased" surface, I unscrew every single bolt/ nut at least every 3 months, usually apply lower torque than on "dry" thread.
If you plan to leave locked thread for longer than 6 months, live/ irde in humid/salty environment , use "light" Permatex/ Loctite (222(?) ).
Heat blower…. do you know TzG ( glass transition temperature ) for CF frame ?
I would be VERY carefull.

I can be wrong, and have plenty of examples for that
