    Works well, be prepared for the mess
    I used this to fix open area after using 3M double sided tape to fit a spoiler on my Supra. There was only one area that had an open area and if I kept it open more dirt and water would go in. It looks super good when done but it’s very very messy. I removed the tape probably around 15 minutes, and it was still in its liquid phase. And boy was it messy. At that point, I wanted to have a cleaner line and I wanted the finish line to sit more underneath the spoiler, but anything I did at this point was smearing. I think it's better to sit and wait until it reaches the rubber phase for cleanup. It's pretty spot on about the timing at the 45 minute to 1 hour mark when it gets to be more rubbery in consistency. That's when I did the best cleanup. I used a small cup of water and dipped a glove-wrapped plastic trim remover (best not to use metal because it'll scratch your paint) and started pushing the edges of the silicone to a straight line. This will leave small smear marks, but it's way easier to clean up at the rubber phase, which I use alcohol pads to help wipe, and still at this point it wipes smeared silicone very easily.

    The rear sliding window on my F250 has an upper and lower slide track. The upper track is held on by 5 or 6 adhesive strips about 1.5 inches each. After 4 years in the Florida sun the strips gave out and the upper track came loose allowing the sliding glass to fall inside the truck. After removing the track and cleaning the surface I applied this adhesive and its holding rock solid. It’s had some heavy storm winds blow on the window and I figured if it was going to fail it’s during storm winds. Not the case. Held up really well during several storms and still strong as ever. A very strong and easy to work with adhesive. Highly recommend.

    I think pretty much all of this RTV sealant stuff is messy. Silicone compounds dissolve in almost nothing, so don’t expect alcohol or acetone to get it off your hands. Best thing to do is use a paper towel to wipe off as much as you can from your hands or anything else you don’t want it on, then use that auto mechanics pumice hand cleaner stuff to scrub the rest off it off (it won’t dissolve it but the pumice will scrub the rest off).

    But this particular product or batch of the product seems unusually difficult to squeeze out of the tube. If this is normal then it should come in a different container like a syringe type thing rather than a tube. I had to use one of those chubby kids pencils as a roller to roll up the end and add leverage to my hand to squeeze it.

    Otherwise it seems to be fine but note that it isn’t recommended for gasket replacement or car windshield sealing because there are specialized formulas for those conditions.

    I had a small length of weather stripping that came loose on the passenger door of my vehicle. Through guidance on the internet I found that this product would seal the stripping. There were many purchasing options, most of which were in larger quantities and much more expensive. I only needed a small amount and it did the job very well. I know I will find many more uses for the remainder of the tube.

    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!
