Permtex gasket maker
Great stuff for what I need it for. I use it in mushroom cultivation. To seal jars and use as injection ports. I recommend to anyone doing the same. Easy to use great price. Durable up to 500°. I use in boiling water no leaks. Easy cleanup

Hi Tim adorable and affordable RTV silicone
One of the best and most affordable brands high temp RTV silicone. I use it for ceiling fittings on liquid culture jars used for mycology so they can be sterilized in an autoclave with no problem. Works great keeps a great seal and easy to use.

This is my new sealant of choice.
Ive tried a lot of sealants. Thsi 90 minute is awesome. Its super messy but that is on me most of the time.I like that I can lay a bead, attach the parts finger tight only, weight 60 minutes, torque to spec, then wait another 30 and drive the car. Other sealants give me anxiety if they are actually dry and ready. Never a leak with this stuff. Confidence is king with this product.FYI I might have gotten the times incorrect in this review. I think that is the right time interval but I dont commit this kind of stuff to memory. Just ready the use instructions before you apply to make sure.
