## Description

General purpose rtv Indoor/Outdoor sealant

Review: great stuff, even worked well in the rain
Review: 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.

## 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.
