Rivnuts on the roof. Which Loctite? Red or Blue?
I am bolting my solar racking to the roof using 3/8" rivnuts and SS bolts.
I want to loctite them to keep the bolts secure but am not sure which Loctite would be best.
The blue will break loose with a wrench. The red is much tougher. If the Blue is secure enough then I am fine with that. If it is not strong enough I can use the Red but it will be fairly permanent.
What do you all suggest?
BTW: I am using closed end Rivnuts and bedding them in 3M-5200. The finished assembly will be covered with self leveling roof sealer. Water should not be an issue.
