Review: Fixed my door seals !!! 10/10 ! Must buy strong hold ! - I read the comments first before purchasing and they were not lying ! So my weather strip on my car both driver side and passenger door start peeling off. I should have made a video so yall can see that this stuff actually works ! Last night it rained and I applied this product before it rained. And guess what I came out side to look inside my car to see if rain got in there ! And yall no rain made it inside my car ! Not even a single drop ! The tackiness is 10/10 ! Yes it’s heat resistant and a cheap fix for fixing your door seals. Now make sure y’all before when squeezing the product out because it can be a little messy , if you’re not careful. But other than that 10/10 so glad I brought this ! No odor smell to it at all and dries fast.
Review: Great adhesive especially for attaching carbon fiber parts to vehicles. - 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.

### ⭐⭐⭐⭐⭐ It’s versatile, and worth the money!
*by C***N on December 5, 2025*

I picked up this Permatex black silicone adhesive sealant for a few small repairs, and it ended up being one of the most versatile products I’ve used. It applies smoothly, cures to a strong and flexible hold, and bonds well to everything from plastic and metal to rubber and glass. I used it on a weather-exposed automotive trim piece and a small interior repair, and it sealed perfectly with no peeling or cracking. Once cured, it’s tough, completely waterproof, and holds up great against heat and vibration. I really appreciate that it’s suitable for both interior and exterior use, which makes it a reliable go-to for all kinds of DIY fixes. Overall, a dependable, long-lasting adhesive that’s absolutely worth keeping in a toolbox.
