Best high temp sealant i have used! Perfect for turbos!
If you are rebuilding turbos, this is the perfect sealant to use for the compressor housing! Very strong and durable! Very good value for money as the tube has enough to do 10 - 20 turbos! Easy to use and apply the head and tube function very well, and doesn't leak when rolled up.

This stuff is brilliant!
Worked a treat to stick stainless components onto my stainless steel bbq. Some earlier adhesions have lasted more than 5 years - very hot whilst in use and subject to weather throughout the year without protection. Impressive

Good price. Goes on well.
Good price. Thick and sticky. Should make a good seal but only time will tell.

Works great, And was Low odour too.
Used to replace the housing to battery compartment o-ring on a Night vision Monocular. Low odour and no nasty solvents given off during the curing process that might damage the Image Intensifier Tube inside the NV Monocular.

It worked well for my use case
It worked wonderfully to seal the holes between the roof rails and the body of the car.
