This is the best high temp gasket seal you can buy in North America. Top quality material and ingredients make this a shelf stable long lasting product that not only keep well but it seals even better. Perfect for those Coolant port seals and any other hight temp leak prone areas. 5 star product and Honest Reviewer approved!

Product was used to seal hot tub TouchPad onto the acrylic tub. Worked fantastic. Tub is used in -30 Celcius with no issues. (Of course applied it when temp was above freezing). Would highly recommend.
