Review: Heavy-duty hold for motorcycle components - Used this for my motorcycle mods and it’s been rock solid. The grip strength is serious — once it sets, things aren’t moving. Perfect for press-fit or cylindrical parts. Just make sure alignment is right before it cures, because it’s not forgiving. Definitely worth it for long-term reliability
Review: Strong stuff - Looks like the real deal. Although when you peel the sticker back it reads "For India Only". My 242 bottle had the same and it is working like it should. This 638 is strong stuff.
