    WD40 is not appropriate for this application.

    Best approach: dissemble piston, clean it, lube lightly with silicone grease, and reassemble. Also lube cables with aerosol silicone grease using cable lube tool.

    Quick approach: work aerosol grease into piston.

    Glad you got it sorted with Steve -- he is always helpful. I find we need to tighten ours up every few months. I totally agree with Chas about choices for lubricants. I never use WD-40 unless there is corrosion -- I learned that the hard way.

    That's the truth. Steve is awesome.

    "WD" stands for 'water displacement' and that's exactly what it is for! You're right to never use it unless you're trying to keep water/rust at bay. It's a crappy lubricant. Metal on metal = grease.

    AFAIK it's not a good choice for water "displacement" either if you leave it. It's miscible in water as is CRC also, which means that although it initially breaks up rust/frees up rusty stuff, the remaining product is a conduit bringing moisture back into the problem area. Best to blow off with compressed air and introduce oil or grease once freed-up.
    Classic example: seizing up air cooled Beetle door hinges.
