I used this to seal around a set of aftermarket rear brake lights after my original ones let water in and ended up getting damaged. Applied a clean bead around the edges and let it cure for the full 24 hours. The day after, we had heavy rain and so far it's holding up great - no leaks and the seal feels strong. It used just over half the tube for both lights, so if you're planning a bigger job or sealing more than one area, I'd definitely recommend picking up two tubes just in case. Will update if anything changes, but so far this stuff is doing exactly what I needed.

Been using Permatex for several decades and this is my go to brand for most if not all automotive sealants and adhesive. This stuff works great for attaching a carbon fiber cover on my mobile antenna. It takes about an hour to lose it's tackiness and about 24 hours to be fully cured. Also keep in mind this black adhesive is messing especially when it gets on your fingers and hands. Just use WD-40 on a terry cloth to clean your hands and all of the black adhesive should comes off with little fuss. This stuff works great and it's been over 24 hours and there's no leaks even with the past two day it's been raining pretty heavy. The for money, it's great stuff to fix and repair or to fill in gaps and holes on many surfaces.

No es exageración. Un apretón (de acuerdo a las instrucciones y si no puedes ver algún video tutorial por si dudas de cómo aplicarlo, yo dudé) y comienza la magia. Es un polvito negro muy fino por lo que guantes o una limpieza de manos a conciencia es recomendable. Las chapas y cerraduras con problemas de que la llave no entra a la primera, se debe aplicar fuerza o rechina simplemente comienzan a desaparecer al paso de la primer aplicación. Yo juegué un poco con las llaves (meter, sacar, meter, sacar, girar) un par de veces para que el polvo comience a esparcirse. EXCELENTE AHORA! Con el paso de los días (creo porque se va distribuyendo mejor) su funcionamiento se vuelve mejor. Sigan las instrucciones y contraindicaciones ya que parece un artículo fácil pero requiere de su atención. Volveré a comprar sin dudarlo. Lo combiné con un lubricante de litio que también compré en Amazon y la verdad hasta gusto me da abrir mis puertas!
