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.
Review: It’s versatile, and worth the money! - 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.

## Questions & Answers

**Q: How can i apply this ao it comes out neat**
A: Make sure surfaces are clean.  Work slowly using the smallest opening in the tube you can.  Check your spelling before hitting 'send'.

**Q: Can this be used to help seal a drainage hole in a resin planter I now want to use as a water feature?**
A: YES it can, as long as it is not too thick.  If the hole is large, use a wood plug or short bolt/screw to fill the void and the Permatex as a sealer around it.

**Q: Could I put this along the edges of convertible top? I don't want to glue the top on, just improve the seal where rain drips in.**
A: Yes it will work. The best way to seal it is to apply the sealant where you want it to stick, and put vaseline on the other surface so it does not stick. This way it will not be sealed shut. The side with the vaseline will not adhere to the sealant and you will get a gasket so your top can go up and down without tearing it apart once it dries. I hope this makes sense.

**Q: Does this work for a crack in a car dashboard?**
A: Probably, it is like black caulk.  Sticky to put on.  I use a popsicle stick to smear it on a spot the removal part of my car top to  fix a leak in the rubber seal.  This stuff is flexible and worked great for that.

### ⭐⭐⭐⭐⭐ Impressive Sealant That Withstands Heavy Rain
*by S***A on December 22, 2025*

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!
