I wanted to wait a while after applying this to my car before leaving a review. It’s been a few months now, and I originally noticed water seeping in through the rear window because of wear and tear on the rubber seal. I was skeptical at first since this product was so inexpensive, but I’m genuinely impressed with how well it sealed the gap. I live in an area where it rains about 80% of the year, and this product has held up perfectly. Two big thumbs up from me!

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.

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!
