    Red or Blue Loctite on replaceable dropouts?

    The Marin manual say compound 638 for the rear replaceable dropouts for my Marin Wolfridge maxle rear. The manual says also coat the outside of the female nut before installing.

    My concern is where it says you have to heat to break it loose to replace the dropout. The only equivalent I could find to 638 is red loctite and it says to heat to 500F to break free. That sounds dumb on a heat treated aluminum frame.

    Would blue loctite work as good? What does everybody else use?

    When I changed out the drop out on the drivetrain side on my 2008 Mount Vision it had a bit of blue locktite on it. Thus I used blue locktite for the the new dropout.

    Red loctite sounds like overkill, I'd try the blue one first.

    Generally the red loctite is considered "permanent" and the blue loctite is considered "removable"
    So blue is correct for the application in question.

    Just pulled the dropouts off the malformed rear section of my Quake today...blue loctite was on the threads.
