Strong, flexible, heat safeI've been using this stuff for years...it's basically my go-to glue at this point. It's the duct tape of glue. It takes a long time to dry, and it does have some fumes but nothing like you get with most strong glues...turn on a fan and open a window and you can use it in the living room without bothering anyone. The hold is pretty strong, it's electronics safe, and it handles a wide range of temperatures. It's flexible too...not to the point that joints feel like rubber, but enough that it doesn't crack when impacted...in fact it has an elongation factor over 3...if you get to that point you probably want it to give out to avoid breaking the parts it's used on. It is more removable than most glues too; you can cut it or twist it if used with metal parts (plastic parts usually break before the glue does). One issue with removing it is that it goes into every little crevice; the little tiny scratches on a surface sanded with 600 grit will be all full of it even after scraping. There are compounds that dissolve it...also sold by Permatex. It also holds oil and most other fluids. It's electrically conductive when fresh but it's an insulator after 24-48 hours. You can handle it gently after 4 hours, thin applications are dry after 24, thick applications can take a couple days to dry all the way through..and by thick I mean 1/2 inch gaps and larger.
Also, if you have something that uses cork gaskets, this is a MUST HAVE. Coat each side of the cork gasket in this and it lasts almost as long as a neoprene gasket...you will tear the gasket to shreds if you need to remove the part later, but cork gaskets are not meant to be reused anyway.
