Très bon produit
Le produit lui même me semble parfait pour remonter un moteur. L'huile adhère très bien aux surfaces, pas besoin d'en mettre des tonnes. On peut faire plusieurs moteurs sans problème. Le produit est visible une fois en place, on sait si on l'a mis ou pas. Le seul reproche c'est le bouchon verseur qui pourrait être plus pratique, là on a un système qui évite d'avoir un bouchon qui se balade mais c'est pas des plus pratique pour étaler du produit précisement.

Useful engine assembly lube
I've been using the Permatex 81950 for a while now and really like how smoothly my engine parts go together. it's handy to keep on hand during rebuilds. the red color makes it easy to see where I've applied it. definitely a good addition for anyone working on engine projects. it helps parts turn easily without any hassle. happy with the quality and how it performs during assembly.
