Ultra Red

Used to seal exhaust manifold gasket on tractor. Several months with no leakage. If using on manifolds, just put a thin bead on both sides of gasket, just around the ports. Also used to seal exhaust studs on tractor that penetrated coolant jacket. No coolant leaks.

Good product never had any problems with it, follow the directions.

Good price, shipped right to my door didn't need run to the store to get it. A little hard in the tube when I opened it might been older tube I dont know? Worked good to seal my thermostat housing. Honestly no complaints.

Great for sealing gbb magazines. Don't spend $$ on mag seal rubbers... They get pinched and most of the time don't work.

This good product and high-quality I didn’t expect it that big it’s enough to make seal with 6 different cars

Used it in the past when I was younger and dumber, but it did work. Some people like to use this as an "extra measure". I can say it held up well enough that I remember having a positive impression of it. Will seal. This is NOT an acceptable replacement for a gasket, but if you ain't got one, it'll get you outta a jam, and there are more specific applications where I use it. A quick-fix if you choose to use it that way, and holds up well enough.

I used this during the build of my second Voron 2.4 3d printer. I used it in the build plate and the heating element. I also used this product on my first build years ago and it is still looking good. I would buy it again.

great product,
