Reply to "Coolant Tank Sealer"

As an update on this subject. The KBS coating will not handle heat, so it's worthless on these tanks. I'm convinced to just replace them with stainless. Even if you get them cleaned out they will be thinner, then the whole process starts over again, meanwhile you are getting lots of rust particles circulating in your radiator and blocking it up! Not worth messing with them.
