Works as advertised
Spot on. Sealed my new temperature sender unit nicely into my thermostat housing. Tested all good.

Leak solved!
Solved a persistent little diesel leak on a compression fitting and much better than using PTFE tape

Thread sealant
Perfect thread sealer. Used on my turbo oil drain as it is a brass fitting that screws into the block. Followed the instructions, nice and easy and doesn't leak. Great product and good price

Excellent stuff
I bought this as I've always had a slight weep on my vans sump plug when i do an oil change despite using a new plug and washer every time i used this and its gone now.. it states it doesn't set so I just hope I can undo it when I do my oil next but im confident it will... iv ended up using on other stuff around the house so its proved more useful than I initially thought

Worked fine at exhaust temperatures
I used it on an exhaust stud that was leaking oil, and it performed perfectly even at the high temperatures involved.

Mix the sealant within the tube as per the instructions.
Follow the instructions properly and mix the sealant be kneading the tube top to bottom. I've applied it to the fill and drain plugs on a transfer box, and two differentials, that's six plugs in total. Not a single drop of oil has leaked out.
