What makes you trust Amazon for Vibra-tite?
Edit to add: Vibra-Tite 530 on Amazon.

I went with the Vibra-tite, because I could trust the legitimacy of the product and I don't trust the vendors selling the Loctite on Amazon and Ebay. The Vibra-tite 530 is comparable to Loctite 609/675 and its shear stregnth is on the low end of the product range.
