Blowing from cylinder into the water jacket

My old V6 had blown its head gasket between a cylinder and the water jacket. Pressurised water system and needing a top up every 50 miles. Cost of fitting a new head gasket is about what the cars worth.
2x bottles of Steel Seal into the header tank and run on tickover for an hour and the problems fixed. Just don't understand how a liquid in the water system can fix a hole against the pressure of a cylinder thats producing huge pressures. But it does.
Now covered 500 miles with no water loss at all.
Not cheap but damn good stuff.
